Audacity Forum

*Open Audacity - File - Open - Double click track Left panel says Stereo 32 bit float. *Highlight track with cursor from right to left - select Effect - Change speed - in box make % change 0.1 and standard vinyl RPM n/a and n/a, click OK and speed changes.... *File - Export (doesn't matter what name...

I don't know how to explain more clearly than I already have... And I've just had the same happen with a completely different file.... Open the original 16bit/44.1 file. Highlight the file with the cursor and increase speed +0.1%, go to export and select FLAC.. Dither is SHAPED. Repeat this except o...

Hello, Yes I am familiar with how to export WAV and FLAC as 24bits..., so I am certain I did not export as 24bit FLAC as you suggested I might have done... I am certain I did exactly the following: Audacity is set at default 32bit float sample format. Imported a 16bit/44.1 FLAC file, gave it a +0.1%...

OK I have Audacity at 32 bit float default sample format. I just loaded a 16bit FLAC file, gave it a +0.1% speed increase, and exported using shaped dither as FLAC. I then went through exactly the same process but exported as WAVE instead of FLAC. The exported FLAC file has quiet hiss in the silence...

Is the column you call "quality preference" on that list the same as what Audacity settings call the "default sample format"? You mention specifically for non-compressed eg. WAV, can you please tell me what happens with FLAC, how does FLAC import/export? PS - I remember 2-3 years ago I was told ther...

Ah so it does actually work with a file imported as 16bit at 32 bits (I was never sure if that just meant you could import a file of anything up to 32bits, but have it work with the file at it's original bitrate (eg. 16, 24, 32), so it seems then that speed changing 16bit and 24bit files technically...

Hello, Thanks for the samples.... OK I think that's where I am confused. I know dither is supposed to be used when downsampling (going from higher to lower bit depth), but when loading a 16bit file into Audacity (with the float point at 32bit), and I export that original 16bit file as 16bit, is that...

OK... I just took a 16bit/44.1 file, applied a +2% speed increase, exported it as 16bit/44.1 with dither set to "shaped", I then did the same process with dither set to "none". I compared the 2 output files and in the silent couple of seconds before and after the music starts in the one with dither ...

Hi, From what I have always understood "dither" is used when "downsampling"? When "speed" (pitch/tempo) changing in Audacity I only ever export at the same sample rate as the original files eg. if originally is 16/44.1, I'll export it as 16/44.1, the same goes for a file that is originally 24/48000,...

I know MP3 is lossy, I never use MP3 at all... I use Audacity for "speed" (pitch/tempo) correcting WAV and FLAC files. Just wanted to make sure those particular settings I asked about are for optimal quality?, and are there any other sneaky settings (like that incorrectly set "dither" setting) I nee...
