Accessories
Too numerous to mention. I got you covered.
These days, the audio tracks I lay down are most often recorded directly to the video recorder at the camera, whatever its format. But the best way is still a two-part system, as done for film. I have a high resolution digital audio recorder with full time code capability (Sound Devices 702t); this can be used as primary audio, or as a backup for the tracks at the camera. I can also backup tracks with an excellent little Zoom MP3 recorder always available in my bag. Backups are especially recommended using a wireless link to the camera, as is common when working ENG-style.
It’s also very common for me to record audio for interview transcription purposes, with or without camera time code: I have several little recorders in various file formats for that purpose.
