What audio file formats are commonly used to store court recording audio?

• A. MP3 or AAC
• B. WAV or FLAC for lossless capture; MP3 or AAC as compressed options
• C. OGG Vorbis
• D. AIFF

Answer: (B)

For court recordings, the important consideration is preserving the integrity of the testimony while keeping storage and access practical. Using lossless formats during capture—WAV or FLAC—keeps every detail of the audio intact, which is crucial for a reliable official record and for any later transcription or review. After recording, creating distribution or access copies with compressed formats like MP3 or AAC reduces file sizes, making it easier to share and store without taking up excessive space. This combination—lossless capture for the original and compressed formats for distribution—best serves both fidelity and practicality.

Ogg Vorbis is a lossy format, which isn’t ideal for preserving the exact, unaltered content of court recordings. AIFF is another lossless option, similar in concept to WAV, but WAV and FLAC are more commonly used in many court reporting workflows for their balance of compatibility and efficiency.
