I’m French so i will probably make some mistakes in this message (I will try to do as little mistakes as possible).
I have a problem when I’m recording. In fact, when I use “play”, there is no problem (I hear normally the track from my loudspeakers), but when I try to record the same track (with the same loudspeakers and a microphone), I do not hear exactly the same track from the loudspeakers (there is a difference between the sound which come from the loudspeaker when I use “play” and when I use “record”). It is the same track, but there is like disruptions.
Does someone have had the same problem or can help me to resove it?
Turn off Transport > Software Playthrough (Passage audio logiciel).
But it is a bad idea to record the speakers with the microphone. You will record in much higher quality using stereo mix or what U hear (if your sound card has that) or with Windows WASAPI loopback. You can use WASAPI loopback if you are on Windows Vista or later.
In the first (Host) box of Device Toolbar, choose “Windows WASAPI”.
In the second (Output device) box in Device Toolbar, choose the Speakers or Headphones that you are using for listening.
In the third (Input device) box in Device Toolbar, choose the (loopback) input for the same device you chose in step 3. For example, if you chose “Speakers” in Step 3, choose “Speakers (loopback)” in this step.
In the fourth (Input Channels) box in Device Toolbar, choose mono or stereo.
I have to use my loudspeakers beacause it is a work I have to do (it is a experiment).
When I turn off Software Playthrough, no sound comes from my loudspeakers and the track mooves very slowly.
Do you have an idea to resolve this problem?
If you are trying to record a track playing in Audacity, turn on Transport > Doublage (Overdub) then you can hear the track.
It might help if you tell us exactly what you are trying to do and why. Are you trying to do a Latency Test ?
Please tell us what version of Windows and Audacity you have (look in the pink panel at the top of this page). You can get the latest Audacity 2.0.5 from here: http://audacityteam.org/download/windows.
Please tell us exactly what microphone you are recording with.
Try choosing 44100 Hz project rate bottom left of Audacity.
I will try to explain my problem:
I have to make an experiment (in physics): I have record a track after it cross a special environment.
In order to do it, I need to use my loudspeakers to play the track, and after to reccord it with my microphone.
I have the version 2.0.5
When I have this configuration (attachment), no sound comes from my loudpeakers when I try to record, and when I just try to play the track it is played 10 times slowly than normal.
Turn off Transport > Enregistrement automatique unless you need it.
What “special environment” exactly? If the environment is a special virtual audio device, your sound card may not be compatible with that environment.
Unless the purpose of this is to measure microphone delay, you should record the computer playback using stereo mix or Windows WASAPI, not with an external microphone.
If a professor has told you to do this, you could ask him/her what the purpose is, or get him/her to help you.
Fix the sound card or turn off the environment that is stopping it working properly.
Is it recording 10 times slower than normal? If so it will play like that.
By environment I mean an area. I do not think that it is important to knowwhat is this area made of, but if you want to it is composed of a grid of cans.
It is not what I do. I have to experiment time reversed acoustics. I have in a firt time to use my loudspeakers to play the track, and to reccord it with my microphone after the sound crossed the area (the sound is modified because of cans).
No I work anone, I just have to do this for work, but Audacity makes me problems.
My drivers are all up to date.
Sorry, I have windows 7.
In fact I can record the sound from my loudspeakers, but when I try do to it the sound from my loudspeakers is modified: my loudpeakers are not playing only the track anymore, but the sound recorded by my microphone in the same time.
In fact, I cannot read just a single track when several track are in Audacity: all the track are reading together.
It may be better to use an external sound generator for these kind of scientific tests.
The drivers must not only be up-to-date. They must also be made by the manufacturer of the computer (if it is a branded computer like Dell or HP) or otherwise by the manufacturer of the motherboard. They must be drivers for Windows 7. If you have Windows 7 64-bit then you must use the drivers for Windows 7 64-bit.
If the drivers are made by Microsoft they are generic drivers not matched to your motherboard. That could be the cause of your problems.
Are you still getting the tracks recorded 10 times too slow, or a correctly recorded track plays back 10 times too slow?
Press the Solo button on the track you want to record.
Turn on Overdub (“Doublage”) - when you press Record, only the soloed track will play.
Turn off Software Playthrough (“Passage audio logiciel”) - if it is “on” then it will play the modified sound after passing over the cans that you are trying to record and mix it in to playback of the soloed track.
In other words, you must go without hearing the recording while you are making it.
If Software Playthrough is off and you actually have correct audio drivers then something else is playing the input through the speakers. Right-click over the speaker icon by the system clock, then choose “Recording Devices”. Right-click over the external microphone then choose “Properties”. Then click the “Listen” tab. Ensure “Listen to this device” is not enabled (not ticked or checked).
Set the Transport Menu to Doublage (Overdub) “on” and Passage audio logiciel (Software Playthrough) “off”.
In the “Enregistrement” Preferences, set the “Audio vers tampon” to its default value of 100 ms. Your choice of 0 ms is the cause of not being able to record with Doublage “on” and Passage audio logiciel “off”. You can record echoes of your sound when you have Passage audio logiciel “on” because when that is on, your setting of 0 ms for “Audio vers tampon” is ignored - Audacity uses an internal value for buffer length instead.
Also in the “Enregistrement” Preferences you have “Correction de latence” set to 0 ms. Perhaps you want that for your experiment, I don’t know. 0 ms won’t stop you recording but it will mean that when you stop the recording, the recorded track will not be realigned with the track above. If you wanted the recorded track to align, you would set it to a negative number.
