Ripping mono CDs
« on: December 08, 2015, 10:57:23 am »

is there any option which makes ripping mono CDs into mono files ? I can clearly see (by aufacity) that both right and left taracks are in the resulting files (flac, m4a np3 or whatever). I remove the unnecessary channel by audacity as well with a huge space saving but it would be grat that this is done automatically (and prserving tags of cousrse)

You didn't ask, but here's my opinion:  Trying to do non-standard things to save space is a recipe for problems later on.  Will every device you want to play your songs on support mono?  Probably not.

This reminds me of VBR encoding in MP3s.  Seemed like a great idea to save space at the time.  It turns out to cause no end to problems with various systems (especially when used in a video container).  Now that hard drives are so much bigger, it seems like a silly solution.

Right now, I think disk space is so cheap that everything audio should be ripped at full, lossless, original format.  In a few years, the disk space will be even bigger and cheaper.

Again, just my opinion.

thanks, neverthess i do this since many years and i never had a problem: flac, mp3, aac support mono/stero encoding and any software claiming doing this should recognize mono encoding (and IME this happens: samsun smarphone, smixZing, bubble UPnp and also JRiver which I am tsting now).
I would immediately abondon any system which refuses to play a FLAC mono file :)

What I am doing is perfecti=ly standard and supported by the stereo.mono bit in the MPEG header

If they are really identical, wouldn't the compression algorithm already save you 50% automatically?

Pretty sure the flac compression algorithm operates on each channel independently. You can specify mono in a flac file, but it then only contains one data value per time interval.

this is exactly what i want: tracks like that plays perfectly and avoid unnecessary data storage. do not understand why ripper does not do that automatically (or at least propose) so i have to go thru audacity
