You'll always have a use for the Zoom R24, whether you're recording musicians or working on an indie film.To various people, using this audio accessory as a standalone recorder could mean many different things. This implies that if you're a musician, you can record a full live band and overdub up to 24 tracks (8 simultaneously) without ever touching a computer. You may record all of your lavalier and shotgun mics in the field and mix them to camera if you're a filmmaker. If you're a photographer, you can utilise the R24 as the playback device at the installation to record ambient sounds for use in a slide show presentation.
