Rip audio from video: doing it cleanly on a production

Ripping audio from video is trivial as a technical act and consistently mishandled as a workflow. The file comes out, it gets called audio.wav, it lands in a Downloads folder, and three weeks later nobody knows which take it came from.

A method that survives contact with post

• Inspect the source first: note codec, sample rate, bit depth and channel count.
• Extract at native parameters, never at a converter default.
• Name the output after the source clip, not after the tool.
• Verify the extract: duration and channel count must match the source.
• Store it next to the video, not in a temporary folder.

Naming that means something

A1234C005_231114_R2EC_48k24b_4ch.wav tells the next person everything. audio_final_2.wav tells them nothing and guarantees a phone call. Include the camera roll, the date, the sample rate and the channel count when they are not obvious.

Batch work

On a documentary with two hundred clips, extraction is a batch operation and consistency is the whole point. Run everything through one tool with one set of parameters, then spot check ten files at random rather than trusting the log.

Rights and confidentiality

Ripping audio from material you did not shoot raises a rights question that no tool answers for you. For your own rushes, keep the process local so unreleased footage does not transit through a third party.
