A listener recently asked me, “Hey Chris. Love the show. Just been listening to you talking with Jim Harold. Question. What does ‘hot’ mean in the context of recorded sound. Cheers.” ~Joff. UK.
My answer:
Usually “hot” is an adjective referring to the high/loud/strong level of audio, as opposed to a levels that are low or optimal. For instance, in practice, if you crank a microphone preamp too much and the level is peaking/clipping, you would say that the mic’s level is really hot, and then you would turn down the preamp in order to bring down the level to a more optimal level. Make sense?

In the analogue world, recording hot meant recording at a level that almost took it into distortion, meaning that you got some warmth from the saturated recording and lowered the noise floor in relation to the recorded sound.
Recording hot in a digital world is likely to produce unpleasant digital distortion unless you are proficient in mic technique and treating the audio input through a compressor/limiter. The noise floor of the recording medium is much less of an issue that in the analogue word, therefore if presented with a mic and a recorder and especially of location, I would tend to bring the input down from hot.
