Convert FTR .trm court recordings
FTR Gold splits a hearing into 5-minute .trm segments that ordinary audio tools refuse to decode. Drop the whole session into DepoAudio and get one clean set of standard files.
What is a .trm file?
FTR Gold (For The Record) is the recording system in thousands of courtrooms. It saves audio as a
series of .trm files — typically one per five-minute segment — so a morning hearing can easily be
dozens of files.
Each segment contains AAC audio, but FTR writes it with a non-standard codec tag (0x4180)
that mainstream decoders don't recognize. The audio is ordinary; the label on it is not — which is why players
and converters that handle AAC fine everywhere else fail on .trm.

Batch convert a whole session
- Download DepoAudio — free, open source, Windows and macOS.
- Drop every .trm segment for the session together. DepoAudio handles the codec tag automatically and processes them in order.
- Pick your output — the same settings apply to every segment, so the whole session comes out consistent.
- Click Convert. FTR sessions can run 4–16 channels; split by channel or mix to stereo as needed.
There's no file count limit — segments are processed sequentially, so memory stays flat even for all-day hearings. And it all happens locally; nothing is uploaded anywhere.

Common questions
What is an FTR .trm file?
FTR Gold (For The Record) saves court recordings as a series of .trm files — typically one per 5-minute segment. Each .trm file contains AAC audio with a non-standard codec tag (0x4180) that most audio tools can't decode. DepoAudio handles this codec automatically and converts .trm files to standard formats.
Can DepoAudio convert FTR (.trm) files?
Yes. Drop all .trm files for a session together into DepoAudio and it converts them in sequence, applying the same output settings to each. FTR uses a non-standard AAC codec tag (0x4180) that DepoAudio handles automatically.
How do I batch convert court recordings?
Drag all your files into DepoAudio at once — SGMCA, FTR .trm, BWF, or standard audio files. Select your output format and settings, then click Convert. DepoAudio processes files sequentially so memory stays flat. There's no file count or size limit.
