I have some problems with recording. A month or so ago i suddenly couldnt record while having playback on. When i recorded another track, while hearing the 1st track, i got the "echo effect" in the start, but after a few seconds it goes very loud, and out of scale, nearly breaking my head...

I'd like to nominate Steve's "Really simple tone control plug-in" http://forum.audacityteam.org/viewtopic.php?f=28&t=21920 for inclusion in the Audacity distribution. I think it would be a boon to those users who are intimidated by the Equalization effect. I'm OK in principle as long ...

Benjamin will test the "not recognised" and "import failure" problems with SVN FFmpeg on Debian. He says he took the Audacity package from Ubuntu 10.10 and replaced ffmpeg-av-match-ext.patch by the patch from bug #176 and built the package (using the system ffmpeg provided by Ubu...

It was weird that if I specifically selected the nightly version of libavformat.so it would say that it was found, when in fact it was using a different version. I think this will be apparent if you look at Help > Show Log. I suspect audacity.cfg has a path to FFmpeg which it falls back to when you...

Is it something you have recorded yourself? The most likely reason reason is "enhancements" like "echo cancellation" in the sound card - turn them off in the sound card control panel. Also try updating the drivers of the sound device you are using. Update the device so that it ha...

What are the C, F, U numbers stated for FFmpeg SVN in Audacity Preferences after you browse and select it? Are you getting the "full checkout" or "bare sources" from "FFmpeg SVN" here? I used the "bare sources" ( ffmpeg-export-2010-11-23 ) F(52.64.2),C(52.72....

Thanks for the information about your Cakewalk hardware and Foobar. I had to Google to find out what I think you are doing, but I assume you are using the Foobar WASAPI output plug-in which provides "Windows Audio Session API exclusive mode output support, allowing bit-exact output and muting a...

or uninstall Ubuntu-supplied FFmpeg? What appeared to happen (not 100% certain about this)... I first tried the nightly FFmpeg while the default Ubuntu build of FFmpeg was still installed, FFmpeg (Ubuntu build) was auto detected, but I could override that by selecting the new .SO file (built in my ...

My assumption is it is "LADSPA Computer Music Toolkit". I believe the package in Ubuntu 10.10 is "cmt". I think that's the same one that I've got on Ubuntu 10.10 32 bit, and although I don't get the same problem that you are describing, it does not appear to be completely stable...

Confirmed on 1.3.13 Nov 7. It's also fairly easy to generate an asymmetrical wave. Generate tone into three separate mono tracks: 220, 440 and 880 Hz at level 0.2. Slide the 440 and 880 Hz tracks so the first peak lines up with the first peak in the 220 Hz track. Mix and Render. -- Bill I'm not sur...
