About mp3 quality:
there is big difference bitween codecs, and the sound that you compress. Some codecs are that bad, that i can clearly hear bubling effect in music, and strange noise in silent places.
I have one track from trance master 21 as i recall.
Metal master - Odyssey of light Solid sleep mix.
If you have wav, please try compress it to 128, 192 and 320.
The first minute of the composition has something, what will make you hear the difference bitween wav and mp3, at least 192 an less.
The echo after vocals, and beep, reverbiration aswell will have strange bubling effect, like boiling water or something.
The best way to hear that bubling is to compress silent music with 24 kbits.
But there is another way. Get Nullsoft dsp plugin for winamp. Choose voice remove effect. You will hear that in almost all mp3. Only 320 kbit with lame codec will have the less of it. But i still can hear that. In 128 it will awfull, just try it.
That's why wav is the best it is cristally clear. it is fully digital. Mp3 is not fully digital. It does not have the wave in it. It only has frequences, with small discrepancy. They just try to make that discrepancy as small as possible, so human brains can't hear or recognize it.
The other thing i dont get is why ppl always want more, but not more quality. Few years back, when ppl had 2-4 gb hdds, they were happy to have 200 mp3. Now hdd are at least 10 times bigger, but many still want 128 kbit mp3s, thousands of shit mp3s are better that 200 wavs. |
I hear that sound in my Surround channels! I REALLY hear it when either:
1. The bitrate is below 256 kbps encoded with ANYTHING OTHER THAN LAME ENCODER or
2. ANYTHING encoded with the Xing encoder.
If you use the LAME encoder and u encode at 192+, this won't be present much but, that's why you have "bad" 320s but "great" 160s! My version of Armin - Communication is 320 kbps but, I think it was encoded with Fraunhoffer because I hear that annoying sound a little in my Surround channels and there are definitely frequencies above 16 khz (Xing cuts all 16 khz+ frequencies). So, that's how I know it was encoded with Fraunhoffer.
