– Recording Audio
Pro Tools is an excellent system to use for recording audio. With LE and M-Powered systems you can record and play back up to 32 tracks of audio using qualified hard drives (check the compatibility section on the Digidesign website to see which drives Digidesign has tested). The big advantage that digital audio recording has over analogue systems is that making copies once you are in the digital domain does not degrade the audio, building up layers of noise and distortion on each subsequent copy – as is the case with analogue tape systems. One of the keys to making good recordings is maintaining a good signal-to-noise ratio. So record using levels as ‘hot’ as you can get them without overloading any of the components in the recording chain. If you are recording 16-bit, this is very important, but with 24-bit systems it is less crucial to keep the signal levels at their maximums. 24-bit systems can record a much wider range of signal levels, so even if the signal is relatively low, it may still be using, say, 16 of the 24 available bits, and if this audio is intended to sound quiet in the mix, you will not hear any low-level noise.
