Re: How can I amplitude modulate one channel with another ?

Have you said what you are actually trying to do? You've said that it's to do with data rather than "audio", but other than that I don't know what your objectives are.

Re: FLAC size and conversion accuracy

2. Is there a way to import directly to 16-bit 44.1Khz? Yes, but don't do it. Even if you import as 16-bit, Audacity still works internally at 32-bit float, so there is still down-sampling during export. If you are only editing, and not doing any processing at all, then to avoid adding dither, you ...

Re: FLAC size and conversion accuracy

1. If the Dither Shape option has such a downside, there must a purpose for it right? It's a fairly small downside really. For 16-bit audio, the dither noise is around -84 dB RMS, which at normal listening levels is virtually inaudible. Yes there's a purpose to it. what is one losing by not having ...

I'm closing this bug as there have been significant improvements to RTL language handling.
If you wish to discus any remaining issues, please feel free to start a new topic.

Re: Macros: Change Pitch intermittently zero'd out

Audacity 2.3.0 Windows 10 I created a macro that speeds up tempo 6%, reduces pitch -5%, and normalizes. Ran it on a dozen projects, worked fine. Then checked some of them just to be sure, and found the last six the change pitch stopped being applied. I checked the macro. As shown in the picture bel...

Re: FLAC size and conversion accuracy

Audacity works internally in 32-bit float format. FLAC files are either 16-bit or 24-bit. There is therefore "down sampling" when exporting from Audacity to FLAC (the sample values are rounded from 32-bit floating point values, to 16 or 24-bit integer values. By default, Audacity applies &...

Re: How can I amplitude modulate one channel with another ?

I thought that, very briefly, something like "mult s1 s2" can do the multiplication The "mult" function works with numbers or sounds. (mult 3 2) ;returns 6 (mult 3 my-sound) ;multiplies each sample in "my-sound" by 3 (mult sound-a sound-b) ;multiplies each sample in &q...

Re: delete all vocals Audacity 2.1.0

I'll go with "not possible".

I'd also recommend updating to the current 2.3.1 version of Audacity. It's available via the Audacity website: https://www.audacityteam.org/download/windows/

Re: How can I amplitude modulate one channel with another ?

Audacity works internally in 32-bit floating point format. Nyquist also treats sounds as 32-bit float. For the "valid" range (not exceeding 0 dB), the numeric values of samples are in the range +/- 1. Therefore, multiplying two sounds that don't exceed 0 dB, the product will not exceed 0 d...
