Dither is always an interesting topic to me. Maybe because I can't here any difference when apllying dither, while others can. Here are two short identical tracks. One has dither added, the other doesn't. All observations will be appreciated. Best, John Test 1 http://schicksville.com/Music/T-1.mp3Test 2 http://schicksville.com/Music/T-2.mp3

My understanding of dither is that it is actually adding noise to the digital audio to basically reduce distortion in the lower value sine wavs...... I also know that to create two mp3 files....you would to have had to dither both files....assuming that you are recording at a higher bit rate and as .wav files...not MP3s...... For the life of me...I couldn't hear any difference in between the files. I couldn't see any difference either (loaded in my DAW) I also suffer from severe hearing loss and tinnitus due to gigging....and not taking the proper precautions.....so my opinion means diddle.

I could not hear any difference but I could see a difference on the screen. Here is a pic of the intro.

Well it's doing something then Colin. Maybe only visual. Or it may be heard with acute hearing. Thanks! Yeah Joro, that's my basic understanding of dither (adding noise to the digital audio to basically reduce distortion in the lower value sine wavs......). My understanding is that it would improve a 16 bit mp3 made from a 24 bit wav (though I don't hear it). Thanks for your input. Best, John

I really doubt you'll hear a difference once the files are compressed into MP3s. I have listened to dither comparisons between WAV files before, and unless the music is at a VERY low level, the difference is subtle; there is a deepening of the soundstage with dither applied, like the vocalist and instruments move back a little from the speakers. I do think, if you are reducing the bit depth of a 24-bit file down to 16-bit, you should use dither.

Thanks Patrick! Since the Industry's broadcast standard is 16 bit 48 KHz I'll be reducing the bit rate from 24 down to 16 every time. Best, John

Yep, television audio is 48k and has been for a long time. Interestingly enough, as the TV industry moves from tape to file-based distribution and into HDTV, 24-bit 48k is becoming the standard. Now in radio, stations often use 44.1k to move their digital audio around, since music CDs and file distribution use that sample rate. When I record my own stuff at home, I usually work in 48k. After I get a final mix I'll do a sample rate conversion to 44.1 for the master. I think I've just convinced myself that 48k is better for mixing. Maybe I'm full of it, who knows?
