Hi there!

I've been converting some old midi soundtracks into waves to slap on a cd. They're played on an old computer with the "proper" sounding Yamaha 32 soundcard, then the audio out goes into my old amp, then back out into the line-in on my new computer. I followed the advice from the IRC channel, to mute all inputs on both cards (except the line-in i'm recording to) and to record in 48khz because of my SB Live being best at that.

Anyway, (i just want to check if thats the best method... it doesn't produce noise that's too noticable).

One of the tracks I was sending to a mate, so I encoded it in Psytel at some fairly low settings, and found it really stunk. I compared it to mp3, and the mp3 sadly comes out sounding better than the aac at a 10% lower bitrate. Ivan might want to take a look at it for his AAC + SBR testing? smile.gif

It's got background noise, a fatboy style pulsing instrument, some er, tones of sorts, and some real bad sounding artificial snares, yet I love it biggrin.gif

Here is a wave of it

And here is the mp3 of it

WinLAME rc2 : Portable Player

And here is the aac of it

Psytel 2.15 -internet

Is there any way to make the aac come out better? And is it any use to you Ivan? smile.gif

I have other tracks that would come out equally bad I reckon. Just say if you want them anybody

I think the problem is with the psychoacoustic model! It seemed ISO did not include midi clips in their listening samples..
