Audio Compression Preferences

Post by GH » Thu Nov 01, 2007 7:46 pm

After several replies,and posts in the help forums,i got my video quality to where im "semi-okay" with,wich is good enough..i guess,so now im on the audio,i know how to compress it and all,but i havent done it for a wile,so when im compresing to Lame MP3 what do i set the kbps as?

That's a bit of personal preference and the demands/complexity of the audio that determines the target bitrate (kbps).

Read this: http://www.animemusicvideos.org/guides/ ... io2.html#2
In plain terms, 128kbps means that you have 128kbits of data each second to describe your audio. This is an ok amount for a codec such as mp3 and is one of the more popular levels for mp3 encoding. Just like video, the quality of your audio encode will increase if it has more kbits/second to utilize. However, a 192kbps mp3 often sounds much closer to cd quality than 128kbps. It's all about storing data and it's a simple fact that the bitrate is a limiting factor.
For MP3, 320 kbps (CBR*) is the maximum and is generally considered nearly indistinguishable to the original CD/WAV track. It's also somewhat wasteful in terms of bit usage for most songs and audio.

128 kbps is the default bitrate for most audio destined for a MP3 player like an iPod. It is the lowest bitrate you'd want to use for most music, anything less starts to introduce noticeable compression artifacts.

192 kbps is a nice medium size - not too much bigger than a 128 kbps file and much smaller than a 320 kbps file. For less complex songs, 160 kbps may be as transparent as 192 kbps.

* CBR = Constant Bit Rate. All kbps numbers I've listed are in CBR, if you use VBR encoding instead (which I generally don't recommend) the same bitrate will give you a slightly better sounding file for the same file size.

Thanks for the help,all this is coming back to me :lol:,im going with 192 kbps
