Capturing Sound
Unlike amateur recordings taken with a mobile phone, DSLR or handheld recorder, my gig captures will always incorporate a multitrack.
Similarly to tracking in a studio live space, most average size venues will close mic the important sound sources for detailed amplification through the PA.
By taking a copy of these signals as well as adding in those sources often left unmiked for live amplification (drum overheads, hi-hats etc.), it is possible to capture the unique energy and musical performances of a live gig in great detail.
By mixing in these detailed signals with an ambient recording of the room and audience, the complete atmosphere of a gig can be recreated.
Mixing and Post Production
The second half of the job is in the mix. A careful balance of tonal shaping and dynamics processing to create an aesthetic that suites the performance.
As with all live production, things go wrong. But a great many solutions are available to account for issues with the recording at least. There's not much you can't do with an EQ and a multiband compressor.
The crucial factor will always be the performance. A live recording is worth a thousand words, there's no second takes — but that's the thrill of real musicians making music in real-time.
