Hi. I'm using lame v3.91. I normally use lame --alt-preset standard for encoding stereo wav files to mp3, and I'm very happy with the results.
I have some cds of older mono recordings that I'd like to encode. Although they are older, they are of fairly high quality for the most part, so I want to do a decent job with compression, with a quality similar to --alt-preset standard.
Currently I use --alt-preset standard -m m to select mono mode. Is this the best way to do it? It seems to use a minimum block size of 128kbps, same as stereo, but I would think to achieve a comparable quality a smaller minimum block size could be used with mono, as there is only one channel instead of two. Would lowering the minimum bocksize with the -b option be appropriate in this case? Is there a different alt-preset which is optimized for mono? What minimum blocksize should I choose to get results comparable to --alt-preset standard on stereo recordings?
Thanks in advance for any help.
