Re: Using chains to insert silence at start and end of file

A couple of ways to do it with mono or stereo tracks: (stretch-abs 1.0 (if (arrayp s) (vector (sim (at 0 (cue (s-rest 5)))(at 5 (seq (cue (aref s 0))(cue (s-rest 5))))) (sim (at 0 (cue (s-rest 5)))(at 5 (seq (cue (aref s 1))(cue (s-rest 5)))))) (sim (at 0 (cue (s-rest 5)))(at 5 (seq (cue s)(cue (s-r...

Re: Using chains to insert silence at start and end of file

Here's what I tried to do to generate silence at the start and end of the track. Unfortunately it's not quite that simple - putting silence before "s" in that way won't work because of stuff to do with *warp* that I don't understand :D It should not crash Audacity though, but I see you ha...

Re: Missing 1 Audio Data

In at least one case it was caused by a silent block file being added to blockFileHash in DirManager::CopyBlockFile() (which shouldn't happen, because silent blocks have no files associated with them) -- that causes the error message to come up in loading when there's no actual error. That problem w...

Re: Science Project?

Because none of your equipment is calibrated you will get only a rough indication at best. What sort of microphone are you using? Most microphones have a deliberately non-linear frequency response. If the microphone that you are using is designed for speech then it will probably pick up the 300Hz to...

Re: Gain Cotrol

Audacity 1.2.3 is obsolete. I would recommend upgrading to Audacity 1.3.9 (audacity 2.0 is due out very soon). I find the best way to control the sound card inputs is from its own mixer/control interface. Look near the system "Time / Date" for a loudspeaker icon and double click (or right ...

Re: Multitrack recording - direct to Audacity or external de

What I'm reading indicates that it's impossible to have Audacity record multiple sources to a multiple tracks. The best you can do is record two mono sources to a stereo track. Am I right? No, some lucky users have managed to get Audacity to record multiple tracks simultaneously. This requires appr...

Re: speeding up and slowing down a wav

Apparently there is a great plugin to do this does anyone know of it. Probably "turntablewarp-ms.ny" available from http://audacityteam.org/download/nyquistplugins (note, the other "Turntable Warping" plug-in is virtually the same, but mono only, whereas this one is mono or ster...

Re: Missing 1 Audio Data

I suggest trying the "Nightly Build" of Audacity - this has cured this type of problem for at least a couple of users. You can download the nightly version here: http://wiki.audacityteam.org/index.php?title=Nightly_Builds. When the next official release of Audacity comes out, you should up...

Re: How do you do Noise Removal on a phone recording?

For a detailed write up, click on the "Tutorials" link at the top of this page.

About half way down that page is a link "Noise Removal for removing steady noise like hum and hiss from all types of audio".

Re: Stereo Mix as source in Windows 7?

I don't use Windows 7 either, but apparently it is based on Vista, so this will probably apply: http://wiki.audacityteam.org/index.php? ... ng_devices
