Audacity Forum

I want to filter out certain frequencies (say 500 to 1000 hz) from a WAV file signal. The easiest way is to duplicate the track, then use a 500 Hz low pass filter on one track, and a 1000 Hz High pass filter on the other track. When you Export the audio the two tracks will be mixed together. Altern...

Have you tried running it with ALSA instead of OSS?

I believe the default format for protools is 24 bit, but there are known problems with some Mac set-ups using 24 bit audio. Can you convert it to 16 bit or 32 bit float before importing to Audacity?

Check the settings in your sound card control panel. Audacity will record whatever audio is sent to it, so you need to ensure that only the audio input source is sent to Audacity and not the sounds from the DAW.

What's your setup? XP / Vista? Desktop / Laptop? Sound card? USB audio device? Audacity 1.3.5? Too much information is better than not enough. If you are using a USB audio device, make sure that it is connected, switched on and recognised by Windows before you open Audacity. If you are recording thr...

I'm guessing it's your sound card too. Has your sound card got a "Line in"? Microphone inputs are far too sensitive for a mixing desk. They expect a signal that is about 1000 x smaller than the output of a mixing desk. You need to use a "Line level input" ("Line in"). M...

I would suggest that the instructions on how to use the time shift tool and then cut and paste to create a single track or sound file be added to the manual. There is no need to cut and paste onto the same track. As waxcylinder said, both tracks will play anyway, and they will be mixed (added) toge...

SUPER by erightsoft and FooBar2000 are both excellent free programs for converting audio files.
"16 bit 44.1 kHz Microsoft PCM WAV" is probably the most widely supported audio format in the world today.
