TDH : Well, we will try to do it easy. No machine through which an audio signal passes (analog as an amplifier, or digital, or whatever) PERFECTLY releases what it is given. It can happen many phenomenom. We cannot list them all, but, for example, one of them is the frequencies response (which are not released with a constant gain). Another one is the harmonic distortion. What is it? If you give it a sinusoid (the purest sound), well it doesn't release an perfect sinusoid, and the sound is not exactly as pure as before. Actually, it added frequencies (harmonics) which were not in the original sound. If we look at the graph of the sound on an oscilloscope, it lose its original form. Maybe it is a little too sharp, a little too plane, or with bents which are not really symetrical, in short it has been distorted. It is the harmonic distortion: you give it a flute, it releases a thing between oboe and violin (no, I'am going too far ;o). A priori, except in the effects where this distortion is wanted, we don't really like distortion ( we want the machine to treat the signal, not to distort it in a way different from the one it has been made for). The harmonic distortion amount measures this propenity to distort what it has not been asked to distort. The lower the better. ?subject=Commentaire Dico ECVST : TDH"> Arnaud LE BOULANGER
THRESHOLD : On some effects (as compressor and noise gates especially), it is a hinge level above or under which the effect applies. If we choose -2dB for a compressor, all that is above -2dB will be compressed. We can choose a threshold for the release or the engage of the effect. ?subject=Commentaire Dico ECVST : SEUIL">Ceedjay
VELOCITY : As far as MIDI is concerned, it is the strength with which we play on a keyboard and which has repercussions on the "strength" of the note which is released. This parameter allows to play stresses and nuances. ?subject=Commentaire Dico ECVST : VELOCITE"> Ceedjay
WAVE : Audionumerical sound file format, used on the Windows platforms. Its suffixe is .wav, and it is not compressed (contrary to the MP3 format). ?subject=Commentaire Dico ECVST : WAVE"> Ceedjay
XLR (eXternal mass Live Return) : Professional connector, with three points: an earth, a cold and a warm points. The signal is said symetrical. This type of connection ennables to easily suppress interferences, and to use longer cables than with an non-symetrical signal. ?subject=Commentaire Dico ECVST : XLR"> Ceedjay
