Audacity Forum

I have read elsewhere that stereo-recording is the best way to restore mono records – your comments are invited Difficult to give a definitive answer - it depends on the equipment, the software and exactly what restoration processes you are using. Probably best to make some test runs and see what w...

If you look in "Start > Control Panel > Hardware and Sound > Sound" and select the Recording tab, is the ART listed and enabled? If not, see here: http://wiki.audacityteam.org/wiki/Mixer_Toolbar_Issues#Using_the_Control_Panel (scroll down a bit to the first picture below the blue text box)

I'm getting roughly the same figure as you autark.
The good thing is that with more tracks in the project the CPU usage remains at about the same level. I've just tested with 16 stereo tracks and I'm getting 18% to 31% CPU usage by Audacity.
I've no idea what Audacity is doing while idle.

Try the Compressor effect.
Here's some ball-park settings:

Threshold: -8 dB
Noise Floor: -50 dB
Ratio: 8:1
Attack Time: 0.3 secs
Decay Time: 2.0 secs.
Make-up gain = tick
Compress based on Peaks = tick

That should substantially boost the overall volume without clipping those peaks.

If the clipping is bad enough to be clearly noticeable then it may be beyond repair. Audio that has been recorded at a very high level (up to 0 dB) and then encoded into a lossy format such as MP3 may produce peaks that are above 0 dB when it is decoded. In this case the audio can be repaired by usi...

I just loaded the newest version of Audacity The newest version of Audacity is 1.3.12 and highly recommended. Audacity 1.2.6 is really old. If you have installed Audacity 1.2.6, uninstall it and install 1.3.12. You may need to have administrative rights on the computer to install the program, but i...

Is a stereo option only shown if the sound card is working in stereo ? Yes. In Vista (and Win 7) the sound card must be set to record 2 channel stereo (depending on the sound card it may default to 1 channel mono). Right-click over the speaker icon in the System Tray and select "Recording Devi...

I've not got Windows 7, but can you order the processes list to get them displayed in order of CPU usage? Does it show the CPU usage? Any of the processes pushing over 80%?

Very nice plug-in vinylivo, I'm sure it will be useful to others. I hope you don't mind if I make a few comments. In XLisp (hence in Nyquist) if you multiply an integer by a float it returns a float, so in the line (setf factl (* (float level) -0.005)) the (float) function is not required. This will...
