Audacity Forum

There are many possible causes for crackle on playback. What sort of computer do you have? What sound card? How are you listening to the music? Does it only occur with particular files? If you try playing the same file another time, will it play OK? Does it still happen if you turn down the volume? ...

Have you checked the recycle bin?

Yes, lots of work. Here's a slightly more complex example: ;type generate (defun saw (pitch dur) (mult (pwlv 0 0.1 0.5 dur 0) (osc pitch dur *tri-table*))) (defun square (pitch dur) (let ((hz (step-to-hz pitch))) (mult (pwlv 0 0.1 0.5 dur 0) (osc-pulse hz 0.5)))) (defun drum (dur) (mult (pwev 1 (* 0...

Here's the problem. See how the waveform has a "notch" in it where it briefly goes to the centre line. I've highlighted one, and there is another one visible a little earlier. firsttrack000.png Those notches should not be there. The strange thing is that they occur at exact intervals of 12...

Wikipedia lists technical details (including number of channels) for many audio formats: https://en.wikipedia.org/wiki/Comparison_of_audio_coding_formats#Technical_details SoX can produce multi-channel files from multiple input files using the "merge" (-M) option: http://sox.sourceforge.ne...

Yes it's possible, but not easy. The number of bits (8-bit) is largely irrelevant to the character of this type of music. More important is the type of synthesized tones, and the character of the tune. Whether it's a Nintendo, Commodore, or other early computer sound system, the important thing is t...

32 channels is the maximum in Audacity.
I don't know of any applications that can make 128 channel files.

I think that an improvement on my previous post would be to mark the mid-point of sample regions with a dot, but when snapping to samples, to include the entire sample region. Here it is totally clear which samples are within the selection and which samples are not:

It appears that Chromebooks have a unique audio device setup. https://www.chromium.org/chromium-os/chromiumos-design-docs/cras-chromeos-audio-server What exactly are you trying to record? Are you able to adjust the recording level so that you get a signal in Audacity that is about half the track hei...

In what way does your computer suck? 2GB of RAM and 500GB of hard drive does not sound too bad (my machine has 3GB RAM and 500GB hard drive, but my old machine was much lower spec than that).

What happens if you try to export the project as a WAV file?
