Recording at 48kHz may be sensible if that matches your other video project settings, though 44kHz is fine quality-wise, especially for voice. Recording in 32 bit is nonsense, even in most professional contexts. 24 bit may be sensible if you suck at setting levels and/or are going to process the crap out of your audio. If you are vaguely competent at recording without clipping and without having your voice drowned out by ambient noise and you're just going to mix it with another audio stream once, 16 bit is absolutely beyond fine. Just to make the point, you could probably record at 32kHz/12 bit without anybody really noticing. Never mind recording 44.1kHz/16 bit to some resonable quality MP3 directly. Anyway, if you're hitting 4GB at 48kHz/32 bit around 3 hours, that implies you are recording your mono microphone to a stereo wav, which seems pretty dumb considering that halves your recording time for no reason. If you're paranoid about quality, recording 48kHz/24 bit/mono should net you around 8 hours recording time. A pretty standard 44kHz/16 bit/mono around 13.5 hours. I'm not familiar with LPs in general, but I think that should be plenty in either case.

Yeah, mono. The SoundonSound Review spells it out in the third paragraph. Another thing you'll find there is that sampling frequency and bitrate of the built in convertors are fixed at 44.1kHz/16 bit, so it doesn't make a lick of sense to store the audio in a file with higher specifications than that.

SupSuper posted:However, a lot of video editing software will mess up combining Stereo audio (eg. game audio) with Mono audio (eg. mic audio), and you'll end up with your commentary only coming out of one channel, which is especially annoying for headphone users. So if you can spare the space, you might wanna keep everything Stereo just to be safe.
