Audacity no sound during playback


Why deserve to I not record in Windows Vista or 7?

On brand-new Windows Vista or 7 devices, you may receive "error opening sound device" once you attempt to record, and/or have no audio input tools (or just "microphone") in Device Toolbar.

To investigate this, exit Audacity then right-click over the Speaker symbol by the mechanism clock and also choose Recording Devices. This opens the Recording tab of "Sound" in the Windows Control Panel. Show then allow all the disassociated and also disabled input tools. For thorough instructions, view Using the Control Panel on the Audacity Wiki.

Many kind of brand-new Windows lapheight, notebook or netbook computer systems only have a single audio input port. This will certainly often be a mono port just meant for microphones. On some devices this single port might additionally be able to accept stereo line level input which is vital to document from standalone cassette decks or HiFi units. See "How to affix your equipment" prior to connecting high output gadgets to a single input.

Why can’t I hear what I’m recording?

To listen while Audacity is recording, permit what is well-known as hardware or software application playthrough as defined below. If you use software program playvia and also want to listen to the input without recording it, you must additionally left-click in the right-hand also (recording) area of Meter Toolbar to rotate on surveillance.

Windows and also Linux

Open the computer"s volume manage panel. In the playback section, rotate off the “mute” checkbox or button for your recording source (commonly “microphone” or “line in”) then turn its volume up. This is well-known as hardware playvia. You will be able to hear the recording via very little bit playwith latency.

You watching: Audacity no sound during playback

If this does not work-related, open the Audacity Precommendations. In the Recording section on the left, put a checkmark in the “Software Playthrough” box and also click OK. This type of playvia has actually latency, so you will hear what you are recording a noticeable time after that. You might also suffer audio breakup.

Mac OS X

Open the Audacity Preferences. In the Recording section on the left, put a checknote in the “Software Playthrough” box and click OK.

If Software Playvia has as well much latency, you could attempt turning it off and permitting "Hardware Playthrough" instead. Unfortunately, via a lot of contemporary Mac hardware, no audio is actually produced using this choice.
For skilled multi-track recordings you might uncover that Audacity"s Software Playthrough has actually unacceptable latency. If the computer"s built-in sound gadget lacks hardware playwith, you can buy an exterior USB or Firewire tool and also hardware monitor with its headphones jack with near zero latency. Alternatively, reduced latency software program playthrough may be feasible utilizing the computer system sound tool.For details, see our Tutorial - Recording Multi-track Overdubs.

Why do my recordings fade out or sound as if they were made in a tunnel?

This issue is widespread on brand-new Windows Vista and also Windows 7 machines. It can also happen on various other equipments if the sound tool is using an effect or a corrective enhancement.

If the recording is fading out after a few secs, look for a "Noise Suppression
" setting you deserve to turn off in the Recording side of the sound tool settings. If the recording sounds like it was made in a tunnel, look for an "Echo Cancellation" setting you have the right to revolve off. If there is no echo cancellation establishing or it doesn"t assist, look for "Environment" sound effects in the Playback side of the sound gadget settings - these will influence recordings of computer playback and also sometimes various other recordings as well.

To readjust settings on Windows Vista and also Windows 7:

Right-click over the Speaker icon by the mechanism clock then choose Recording Devices to open up the Recording tab of "Sound" Right-click over Microphone and also choose Properties Tright here will certainly most likely be an Enhancements tab wbelow you can disable all or schosen "Sound Effects" - if demands be, also look in the Levels or Custom tabs If you have to readjust environment settings, click the Playback tab in the main window of "Sound", right-click over Speakers, select Properties then click the Enhancements tab.

Why is my brand-new track out of sync via the previous ones, or sounds crackly or at wrong pitch?

When you make an overdub recording (listening to an existing track while recording a new one), computers can not lay dvery own what you record at the specific immediate you sing or play in response to the beat. As such without treatment, the recording inevitably gets lhelp dvery own after the beat. Audacity tries to correct for this "recording latency" immediately by pushing the taped track backwards after recording stops, however better adjustment might be needed.

If a brand-new track is not synchronized through the others, you can zoom in and also use Time Change Device ( shortreduced F5 ) to drag the track to the correct place. If you are doing a lot of overdubbing, try our Latency Test to set a custom worth for Audacity"s latency correction which can then be used in Recording Preferrals.


Tutorial - Recording Multi-track Overdubs gives a step-by-action overview for manually correcting for latency.


Recording while playing is much more demanding for the sound gadget than sindicate recording. Hardware and sound driver troubles or sample rate mismatches in between Audacity, the operating system and also the sound tool can cause negative audio quality or make tracks play and document at various speeds. If a new track is being tape-recorded at a different rate, it will certainly significantly drift apart from the beat of the various other tracks, so latency correction will certainly never before synchronize it properly along its entire size.

To solve rate drift, pitch and also top quality problems, attempt the following tips.

Use the same tool for playback and recording. If you are recording through a USB or Firewire interface, sample prices and also variety of recording channels must be the exact same all over. Match the Audacity project price and the number of recording networks collection in the Audacity choices with those specified: in any software regulate panel the tool has on any hardware control the device has

Why perform I acquire crackles, pops, or distortion once the recording is loud?

If you hear crackles, pops, or distortion as soon as the recording is loud, or if the wavedevelop is plainly emotional the height and bottom edges of the track, you probably have clipping, which means that the signal has actually surpassed the maximum enabled level.

Try lowering the record level using the Audacity Mixer Toolbar or lower the volume of the input source (like the tape player or microphone, whatever before is developing the sound, if it has actually its very own volume control). Many sound cards and USB turntables/tapedecks also have an independent volume control for each of the input relations, which offers you one more location to change the signal"s amplitude.

When recording try to aim for a maximum optimal of approximately –6 dB or 0.5 if you have your meters set to straight rather than dB. You have the right to always rise the level later via the Amplify or Normalize effects after you have actually completed your editing and enhancing. Enlarging the Meter Toolbar by clicking and dragging on it may assist to gauge levels even more accurately.


Aid through repairing clipping:

If tbelow is just a little little of clipping (simply the tops of a few isolated peaks), Effect > Clip Fix can be applied to simply the clipped sections. This will attempt to rebuild the absent peaks by interpolating the lost signal. In various other cases wright here tright here is mild distortion throughout a recording, making use of Effect > Equalization to minimize the greater frequencies deserve to help to minimize the damage. Sometimes a bass cut will certainly assist likewise by making the result sound less "muddy".

How can I record without little skips or duplications?

If it sounds choose recording is skipping, or little pieces are occasionally absent, this means that Audacity can"t compose the audio to disk fast enough to keep up through what it"s recording. You may not hear skips while listening throughout the recording, yet you will hear them on playearlier.

Audacity settings

Computer and also hardware

Tright here are many feasible actions you deserve to take. Some may have actually no effect on a skipping trouble, others might have actually a cumulative beneficial effect, so attempt them all.

On Windows, on a regular basis defragment your difficult disk drive (this have to take place automatically on Windows Vista and also later, but do not schedule defragmentation during a recording). Disable Windows Upday while recording. Consider creating hardware or software program prodocuments that fill only crucial hardware and also services for a recording session. Set Audacity to a higher priority in the operating system. If you are utilizing a USB recording gadget. affix straight to a USB port, not a hub.

Why does my recording store pautilizing automatically or why is my recording cursor stuck?

Sound Activated RecordingThe recording cursor deserve to legitimately appear to be stuck in Audacity if you have actually accidentally allowed Sound Activated Recording in the Transport Menu and the current recording input is listed below the threshold level at which recording is collection to start. You can tell this is the instance because the blue Pause button will be depressed after you press Record.

To disable Sound Activated Recording, click the Transport menu and also uninspect Sound Activated Recording (on/off).

To make a Sound Activated recording commence, rise the input level, or mitigate the "Activation level" at Transport > Sound Activation Level....

Out of resourcesIf you have actually not caused Sound Activated Recording and also the red recording cursor won"t relocate from the position wbelow you start to record or stalls while recording, this generally means you are out of computer sources.

Rebooting the computer system may resolve the trouble.

For an comprehensive method to reresolving this please watch the Managing Computer Resources and Drivers web page in the Audacity Wiki.

Preferences: Audio to bufferAlso inspect the "Audio to buffer" setting; click Edit > Preferrals then click the Recording tab.

This need to generally be set to the default of 100 milliseconds; very low settings will certainly prevent the recording starting.

USB turntables and also tape decksReports of recordings from USB turntables freezing or having actually dropouts are not that uncommon. Typically they are not resulted in by Audacity, but by bad top quality devices and also cables, or absence of sufficient USB bandwidth.

Check the Project Rate bottom left of the Audacity display is set to either 44100 or 48000 Hz - establishing an extremely high rate might overpack the USB bandwidth and also reason transmission difficulties Check the USB cable for tightness at both ends and also try using a different cable rather Almethods usage a spare USB port, not a hub Limit USB bandwidth whilst recording by using various other USB devices sparingly e.g. sindicate disconnecting from the internet might aid if you usage a USB modem for internet accessibility. Check for any type of system warnings (e.g. in Device Manager in Windows) around the Universal Serial Bus Controllers.

If the red recording cursor moves across the screen but no waveform is attracted behind it (just a flat line), you have to start from the start and also put up your recording device and also input source properly.

Tip 1: input device

Select the input Recording Device you are making use of (such as microphone or line-in) in the drop-down selector of the Audacity Device Toolbar. The drop-down selector you require is the one through the microphone symbol.

If you are plugging a microphone or line-in input straight into the jacks on the computer, or recording computer system playback such as internet radio, pick the name of the built-in sound gadget or sound card.


By default, Windows Vista and 7 just permit the microphone input. You must exit Audacity, then go to "Sound" in the Windows Control Panel to present and also allow other inputs before you can record from them. Instructions have the right to be discovered here in the Wiki.

If you are connecting an exterior device to the computer system, such as a USB sound card, USB microphone or USB turntable, choose "USB Audio Codec" or comparable.


Detecting USB and also Firewire devices:If Audacity does not recognise the device, try exiting Audacity and also relaunching it, or in present Audacity pick Transport > Rescan Audio Devices. If that does not help: Exit Audacity Unplug all other USB gadgets, then switch off and unplug the recording gadget at the USB link and at the mains (on Windows, usage the "Safely Rerelocate Hardware" icon in the System Tray) Plug the recording device right into a spare USB port (not a USB hub), and switch it on Wait a few minutes then entirely shut dvery own the computer and also restart it When the computer has actually finimelted rebooting, launch Audacity.

Setting sample prices for USB/ Firewire interfaces:It"s vital to set the same sample rate in the project price bottom left of the Audacity window, in the operating mechanism mixer, in any kind of settings in the device"s manage panel and on any type of controls on the gadget itself.


Tip 2: output device

Also in the drop-dvery own selector of the Audacity Device Toolbar choose the output devive you are making use of, commonly this will certainly be your computer"s on-board sound card. The drop-dvery own selector you require this time is the one through the loudspeaker symbol.

Step 3: channels

In the Audacity Device Toolbar set the Recording Channels to 1 (mono) or 2 (stereo) as required.

Step 4: input signal level

In the Mixer Toolbar, change the input level using the input slider (the one that has actually the "microphone" symbol) in conjunction with the recording level meters on the Meter Toolbar to set the correct recording level before founding to document for genuine.

If the Audacity input slider does not control the recording level of the gadget, use the slider in the operating system instead. This is commonly accessed by a loudspeaker symbol close to the device clock.

Why do I get an unbalanced stereo recording?

Is Audacity collection to document in stereo?

If you are recording a stereo source and the left or ideal channel is weak or non-existent, first make certain you have Audacity collection to record in stereo.

Do this by setting "Recording Input Channels" to 2 (stereo)  

*
in the Device Toolbar. Your taped track will then say "Stereo" in its Track Control Panel and 2 channels will be displayed as soon as you push the Record
*
switch.

Make sure your physical recording relationships (plugs and also sockets) are tight and also clean. Encertain that any kind of balance controls, on for instance your mixer or amplifier, are centrally placed.

Make certain the left and also appropriate channels are balanced in the system mixer. On Windows this is the recording area of Sound, Sounds and also Audio Devices or similar in the Windows Control Panel (which you can accessibility by pushing the Windows vital on your keyboard), or on Mac OS X 10.2 or later on this is Applications > Utilities > Audio-MIDI Setup: Audio Devices.

Normalize

If you cannot correct the imbalance at the input stage this can be corrected after the recording has been made utilizing the Normalize effect.

This will scale the volume of each channel separately to -6 dB (6 dB less than the distortion level) so they are at the exact same volume level.

Adjusting the Channels Independently

Conversely you have the right to click the downward pointing arrow in the Track Control Panel to reveal the Track Pop-Dvery own Menu and and choose Split Stereo Track from the food selection. This allows you to separately edit and also manage the left and best channels.

Using the Gain SlidersPress the green Play button or Void and also use the obtain sliders

*
on the Track Control Panels of the left and appropriate networks to adjust the gain on each to your satisfaction as the track plays. Note this is not an edit of the wavedevelop so it will not change appearance, although the obtain changes are respected when you export the audio. To modify the waveform itself so you have the right to check out what the exported waveform will look prefer, select the audio and also usage Tracks > Mix and Render.

If you are changing the get on the tracks via the gain sliders, make certain prior to you export the audio that you do not apply too much gain so that the outcome distorts. You have the right to examine this by looking at the green VU Playearlier Meter in the Meter Toolbar.

Using the Amplify EffectIf you choose to adjust the get on each track to an exact level avoiding any danger of output distortion, click in the Track Control Panel of the left channel to pick it and then usage Effect > Amplify picking your forced New Peak Amplitude (the box underneath the slider). Then repeat for the ideal channel and also amplify that to your liked New Peak Amplitude. You need to amplify both networks individually if you want to adjust the balance in between them.

Unlike making use of the gain sliders this will modify the wavedevelop and the outcome will display in the waveform screen.

Remake the stereo trackAfter the amplitude adjustment, you will certainly must rejoin the split tracks to make a stereo track as soon as even more. To do this click on the downward pointing arrowhead in the Track Control Panel for the optimal track of the 2 and in the drop-dvery own food selection select Make Stereo Track.

Why is the recorded wavedevelop not focused on the horizontal line at 0.0?

Causage and also impact

This off-establishing of a signal from zero is recognized as DC offset; a signal via DC offset would show up in the Audacity default Wavecreate view not centered on the 0.0 horizontal line.

A sound that has DC offset will certainly not be at its loudest possible volume when normalized or ampli (because the balance out consumes headroom). This difficulty deserve to possibly extfinish to the mix in its entirety, considering that a sound via DC offset and also a sound without DC offset will certainly have actually DC balance out when blended.

DC balance out have the right to reason inaudible low level distortion (which becomes audible once other filters are used or if the sound is compressed upon export). It deserve to cause clicks at the start and also finish or distortion after running results.

Removal

If this is the situation through your recording, to rerelocate the DC off-collection use Effect > Normalize.

Placed a examine mark in the

*
 Rerelocate any type of DC offset... box but leave the
*
 Normalize maximum amplitude.. box unchecked and then push the OK button.
