Re: Audacity could be more helpful when paused ...

Let's remember the reason for starting this thread - it wasn't about the ability to do "stuff" while paused (how many folk actually want/need to do that?) - it was about helping hapless folk like the thread linked to in the initial post who can't figure out why "stuff" doesn't w...

Re: Unwanted silence added after exporting in Mp3

But that doesn't help blast for his game playback Problem. The great question is how the mp3s are decoded within the game I prefer the question "why use MP3"? If space allows, WAV ( or headerless PCM) could provide high quality sound, more efficient decoding and gapless looping. If space ...

Re: Unwanted silence added after exporting in Mp3

lame has a delay of 576 samples (half of the mp3 Frame size). Is that correct? I thought that the overall encoder/decoder delay was undefined, hence the addition of metada by some encoders to enable gapless playback to be faked (a feature supported by Lame). 576 samples is the size of one "gra...

Re: How to Generate Arbitrary Waveforms as Envelopes

Is something like this beyond the scope of an Audacity plug-in? Designing a nice interface would be tricky, but the basics of entering a list of numbers and creating an envelope from them is pretty easy. Nyquist provides a set of functions for creating "piecewise envelopes", which take li...

Re: Audacity has killed sound on my PC for other programs

Firstly, the "death" of sounds on your PC has nothing to do with Audacity. It is almost certainly due to Windows assigning the USB device as the default output when you plugged in the USB device. Audacity does not control the Windows sound system, it just accesses it. I have disabled the U...

Re: How to Generate Arbitrary Waveforms as Envelopes

A more complex example. Try applying this to a generated tone:

Code: Select all

(setf adsr (pwlv 0 0.05 1 0.3 0.4 0.5 0.4 1 0))
(setq wiggle 0.3)
(setq wigglerate 3)

(setf envelope
  (sim (mult adsr (- 1 (* 2 wiggle)))
    (mult adsr wiggle  (sum 1 (hzosc wigglerate)))))

(mult envelope s)

Re: How to Generate Arbitrary Waveforms as Envelopes

If it is a relatively simple envelope, you can use the Envelope Tool: http://manual.audacityteam.org/o/man/envelope_tool.html If you want an envelope with dozens, or even thousands of points and have a formula to generate the points, it would be possible to create an envelope using a Nyquist Script ...

Re: beep failure

No beep on Linux with or without your patch.
This looked hopeful as an explanation, but it is marked invalid : http://trac.wxwidgets.org/ticket/14899

Re: beep failure

Is this likely to have any effect on Linux where currently beeps don't work at all in Audacity?
