Hi,
Every time I sample something the file is in 32bit.
My soundcard only does 24bit (like most, never heard of 32bit DAC/ADC).
I like to sample at 24bit, is there an option i’m missing?
Thanks
Very quickly: 32bitfloat (which is what Renoise uses) is the full 24bit information, plus other floating data that gives things like DSPs extra breathing space to do accurate processing. In recording this is fine, your hardware understands the 24bit, and then once it’s being shunted around in your DAW you get the bonus of the full 32bitfloat range. Roll with it 
The fact that your hardware is only 24bit is only an issue when outputting to external hardware for purposes of mastering or doing round-trips to process audio in-out-in. In mastering I use a real time dither to neatly output 24bit from the 32bitfloat realm, meaning that my hardware is getting pure 24bit information. This matters, but it’s pretty esoteric.
In short, when recording it’s perfectly fine that you’re recording 32bitfloat when your hardware is 24bit. Nearly everyone here is doing the same and it’s no issue, as far as I understand.
In other words there is no option for this?
The reason I ask is because those extra 8 bits are redundant and the project becomes bigger without the need for it.
I don’t know about processing though.
It’s fine renoise works with 32bit internal, but could it not store at 24 bit and load the sample into memory and then convert to 32 bit?
When I talk about sampling I use my soundcard to record a synth. This is only 24 bit…
Systems are pretty large and fast these days, no? I’ve haven’t been at risk of filling HDDs with audio data since… 2004! Unless of course you’re stuck on a really old system.
By default Renoise stores files as FLAC.
You could also unzip the XRNS, and re-compress the files in OGG. Several apps out there exist to help you.
So yes, short answer is there is no option for this when recording with Renoise. And like MMD explained, it doesn’t affect your recording.
If however the reason is “I need more space” then there are options.
