Aha! The secret of a good MP3...
Oct. 15th, 2006 07:21 pmOk this is one for you podcast g33ks out there...
The last two shows I've been struggling to try and up the quality bar without losing file size - the trigger was hearing how much better I sounded at 128Kbs for the hijack show.
I knew VBR was the answer but had real problems with artifacts when I switched from 80Kbs CBR @ 22Khz to 44Khz on my voice (thinking that higher 44 = quality, right?)...actually I was wrong, 22, 24 or 32 are perfectly good according to this guide http://jthz.com/mp3/. Their settings are great and I'll be using them from now on, these people know their shit.
Listen to the latest Radio Clash http://www.mutantpop.net/radioclash/archives/2006/10/15/rc-94/ and I think you can hear the difference...
I'm now using LAME MP3 Codec (I was using the fHg based built in MP3 export, which I was never totally happy with) which is a two-step process (I wish you could properly do command line LAME export direct from Audition - it surely can't be that difficult? I wish I knew C since the source for the CoolLAME plugin is available, but it only lets you tweak it a little and you can't put your own command line switches in (geeky, but essential for LAME) and thus the results are shite).
I solved one problem (the weird artifacting) my making sure my voice was mono with a stereo imager plugin - I record in stereo, but it seems to confuse the codec at low rates < 96kbs, especially on LAME.
Thinking of doing slightly shorter shows also so I can bump up the encode rate...it's a bitch that I'm on the dividing line where full 44khz audio doesn't work - 96Kbs sounds nice and crisp, but adds a lot more and at the 75min mark pushes me over the max 50Mb limit for files on my host. The reason I want to go for a higher rate is that the CD quality files and remixes are usually OK, but the mashups which have usually been re-encoded several times or have funny phase vocal extraction on them (I'm looking at you DJ Earworm) and are at lower rates sometimes sound odd or watery on the treble end, or do weird stuff with the stereo spectra.
So I'm now recording at LAME -V8 vbr-new 32Khz (yes some older Flash players will probably freak, but hey they should subscribe rather than leeching my bandwidth! :-D) and it sounds pretty good.
I bet you all thought I just rolled up, pressed record and it just all automagically happened...;-)
