MP3 (Lame 3.92) Spectral and Frequency analyses.
this is a series of screencaps showing the characteristics of mp3 encoding at various settings applied to the same lossless wav file. CEP 2.x was used for SA/FA. Thanks to kotti for linking these a long time ago at STG.
original wav SA FA (shown for comparison alongside all FA links here) 256 cbr SA FA 192 cbr SA FA 128 cbr (the most common) SA FA 128-256 vbr SA FA 128-192 vbr SA FA 64-256 vbr SA FA

Re: MP3 (Lame 3.92) Spectral and Frequency analyses.
I have CEP2, I've been playing around with it. How
do I post it. When I use CEP2 it gives me a pk.file, can I use maybe paint, then post a wav file? No members have liked this post.

Re: MP3 (Lame 3.92) Spectral and Frequency analyses.
with cep open & displaying what you want to see, use alt+print screen then open paint and paste (ctrl+v) then save. ctrl+print screen will capture the entire display if you need that. the pk file is just information cep uses to "draw" the wav which has a matching name in the same folder.

Re: MP3 (Lame 3.92) Spectral and Frequency analyses.
Spectral analyses are good, but I do not listen with my eyes. I would suggest that ABX comparisons between the samples would be more valid. To save all the effort, you can search www.hydrogenaudio.org which has done extensive testing between various file types, both lossy and lossless. Also, a more recent release of the lossy types would be better.

Re: MP3 (Lame 3.92) Spectral and Frequency analyses.
Very very cool Five, this is great reference and teaching material!
Thank you! As for listening with our eyes...that is a good point brought up by boojum, but our brains have much more computational organic "hardware" for visualization than for audio processing. So there is a place for "listening with your eyes" as well as the more conventional ways of listening... Besides, haven't we all "listened to the colour of our dreams" before
