Re: 32-bit float to 24-bit: To Use Dithering or Not?

So, are you saying it's not a good idea to do simple cutting on a 24-bit audio file in 32-bit float mode without using dithering? And if so, is there a reason why Audacity can't natively handle 24-bit files without being in 32-bit float mode, just as it can do with 16-bit files (16-bit to 16-bit w/o...

32-bit float to 24-bit: To Use Dithering or Not?

If importing a 24-bit FLAC file into Audacity and doing some minor edits such as trimming and not processing, is it advisable or not to disable dithering? I read that if importing a 16-bit WAV file and doing non-processing type edits, it's best to select 16-bits for the Default Sample Format selecti...

Re: Configure Error Compiling Audacity 2.0.5

As far as I know, Audacity uses wxexpat rather than expat - but expat can't be disabled in configure. It looks like wxexpat is for Windows: http://wiki.wxwidgets.org/Library_files_under_Windows, and is found in no RPM for Linux. Can you try checking out HEAD instead: svn checkout http://audacity.go...

Configure Error Compiling Audacity 2.0.5

When trying to compile Audacity 2.0.5 on OpenSuse 13.1 x64, I'm getting the error:

Code: Select all

configure: error: Audacity requires expat to be enabled
I have expat and libexpat-devel installed. I have searched online and haven't came up with much. How can I correct this?

Re: ALSA Latency

Doesn't the (hw) device also have low enough latency? Yes, but PulseAudio adds latency to the Linux sound system, and since Audacity by default routes to the default device which on a distro that uses PulseAudio will be the default, it introduces issues beyond what I've described. Crashing and scra...

Re: ALSA Latency

Thanks for the info; that has fixed my problem. I lowered the "Audio to buffer" down to 5ms, and changed the output to dmix in the drop-down menu on the Mixer Toolbar. If both of these options are not set, e.g., lowering the latency but not routing through dmix or vice versa, the latency is too high...

ALSA Latency

Hi, I am having a problem with Audacity 2.0.4 on OpenSuse 13.1. If I highlight a small section on a track and play it, no sound is generated. I thought that this latency may have had something to do with PulseAudio, but the same thing happens when bypassing Pulse. Is there a way to fix this short of...
