The thing is, vinyl is all more or less of the same volume. If you start combining MP3s from different sources, that's where the problems start. Because if you, let's say downloaded one mp3 from the net, recorded one of vinyl, one of cd, they'll most likely be of different AUDIBLE volume, even if all files are normalized (to 0dB). Which means LOUDNESS does NOT equal level. So even if two mp3s are the same LEVEL...

Couin, you are right, but keep in mind, an automatic batch analyzer for SSL is planned.

Exactly, what I wanted to say is : don't put the plough before oxen

sixxx, dont forget, with SSL you have tracks from different sources, like from CD (which are mostly maximized allready) and then from vinyl and maybe tape or so. So you end up with different volumes, unless you take really much care into making the sounding the same volume. So, I think autogain is a usefull function.

1) Why you can't use the gain knob on the mixer??? why touching the gain at the software???
2) A DJ should determine the gain volume by his ears and not by leds or auto gain functions.....

Look. Not all vinyl or all CD's sound the same. Not all are mastered in the same place using the same specs. So, I don't buy your excuse. Just face the fact that dj's are getting very lazy now.

DISC JOCKEY... not DISK.

The name "Disc jockey" developed in the era when the only sound recordings available were disc records. For the reason it's disc jockey rather than disk jockey, see disk or disc. Disc is more often spelled "Disk" in the USA.

Disk or disc?

The divergence in spelling is due in part to the way in which the words originated. Disk came into the English language in the mid-17th century, and was modelled on words such as whisk; disc arose some time later, and was based on the original Latin root discus. In the 19th century, disc became the conventional spelling for audio recordings made on a flat plate, such as the gramophone record; this usage gave rise to the modern term disc jockey. Early BBC technicians differentiated between disks (in-house transcription records) and discs (the colloquial term for commercial gramophone records, or what the BBC dubbed CGRs).

By the 20th century, the c-spelling was more popular in British English, while the k-spelling was preferred in American English. In the 1940s, when the American company IBM pioneered the first hard disk storage devices, the k-spelling was used. In 1979 the European company Philips, along with Sony, developed the compact disc medium; here, the c-spelling was chosen, possibly because of the predominating British spelling, or because the compact disc was seen as a successor to the analogue disc record.

Whatever their heritage, in computer jargon today it is common for the k-spelling to refer mainly to magnetic storage devices, while the c-spelling is customary for optical media such as the compact disc and similar technologies. Even in the computing field, however, the terms are used inconsistently; software documentation often uses the k-spelling exclusively.
