Are there any good alternative downsample formats/commands?

Postby NssOne » Fri Dec 24, 2010 9:46 pm

I was just thinking about what could be better ways to downsample audio files to get similar quality audio over 3G on my Android without using as much bandwidth, hence using less of my data plan. Are there other codecs like OGG or AAC that could possibly pull this off? Or a better way to set up LAME to give me better quality encoding for smaller bit rates?

I use OGG for low bitrate files that sound pretty decent on my phone.

EDIT: I have figured out the ogg transcoding parameters, but if anybody has any good quality:file size parameters, feel free to add them. I would like to see how good I can make this.

Have a read of
http://sourceforge.net/apps/mediawiki/subsonic/index.php?title=Transcoders#Setting_up_transcoder_chains

As for actuall parameters I recommend you read the lame man page (run man lame or go to http://linux.die.net/man/1/lame). I suspect variable bit rate (VBR) is what you will want (--vbr-new). You could also use "joint stereo" (-m j) instead of "stereo" (-m s).

So maybe something like...
Code: Select all
lame -q2 -mj -V6 %s -

and i suggest you read:
http://wiki.hydrogenaudio.org/index.php?title=LAME and their discussion forums

for you don't need to fiddle with all those extra switches
