How to Convert TRM Files to Text: 4 Methods Compared [2026]

If you've ever received a court recording and found yourself staring at a file ending in .trm with no idea how to open it, you're not alone. TRM files are one of the most common — and most frustrating — file formats in legal practice. They contain court audio that you need, locked inside a proprietary format that most software can't touch.

This guide covers everything you need to know about TRM files: what they are, why they exist, how to open them, and how to turn them into usable transcripts without losing your mind in the process.

What Is a TRM File?

A TRM file is a proprietary audio recording format created by ForTheRecord (FTR), the digital court recording system used in thousands of courtrooms across the United States, Canada, Australia, and the United Kingdom. When a judge, clerk, or court operator records a proceeding using an FTR system, the output is saved as one or more .trm files.

TRM files are more than just audio. They contain:

• Multi-channel audio — separate tracks for the judge's bench microphone, attorney tables, witness stand, and courtroom ambient sound
• Session metadata — case numbers, timestamps, court identifiers, and recording session information
• Channel assignments — labels indicating which microphone captured which audio stream

This rich metadata is what makes TRM files valuable for court reporting and transcription. It's also what makes them difficult to work with outside of the FTR ecosystem.

Why Can't I Just Open a TRM File?

The short answer: TRM is a proprietary format. Unlike MP3, WAV, or MP4 files that any media player can handle, TRM files are designed to work exclusively within the ForTheRecord software ecosystem.

If you try to open a TRM file with:

• Windows Media Player — it won't recognize the format
• VLC Media Player — it may attempt to play it but typically fails or produces garbled audio
• QuickTime — no recognition
• Audacity — cannot import the format
• Most transcription services — they'll reject the upload

This creates a real problem for attorneys and paralegals who receive court recordings from clerks and need to review or transcribe them quickly.

Method 1: FTR Player (Free, But Limited)

The official way to play TRM files is through FTR Player, a free desktop application provided by ForTheRecord.

How to use FTR Player:

• Download FTR Player from the ForTheRecord website (fortherecord.com/access)
• Install it on your Windows PC
• Open your TRM file through the player
• Use the multi-channel controls to isolate individual speakers
• Adjust playback speed as needed

FTR Player limitations:

FTR Player is designed for playback, not transcription. You can listen to the audio and manually take notes, but there's no built-in way to generate a transcript. If you need a written transcript, you'll need to either transcribe manually while listening (which takes 4-6 hours per hour of audio) or export the audio to a standard format and send it to a transcription service.

Exporting from FTR Player:

To get audio out of a TRM file using FTR Player, you can use a workaround involving the FTR Web Player and Chrome's developer tools:

• Upload your TRM file to FTR's online player
• Open Chrome Developer Tools (F12)
• Go to the Network tab and filter by "Media"
• Play the audio
• Right-click the media file that appears and download it as an MP4

This process works but it's cumbersome, especially if you're dealing with multiple files or long recordings. Each file must be exported individually, and you lose the multi-channel metadata in the process.

Method 2: FTR Justice Cloud

If the court that recorded your proceeding uses FTR Justice Cloud, you may be able to access recordings directly through the cloud platform. FTR Justice Cloud allows authorized users to:

• Stream TRM audio through a web browser
• Order transcripts directly through the platform
• Access FTR QuickDraft, an AI-powered rough draft service

The availability of FTR Justice Cloud depends on whether the specific court has adopted the platform. Not all courts that use FTR recording systems have migrated to the cloud platform, so this option isn't universally available.

Method 3: AI Transcription With Native TRM Support

The fastest path from a TRM file to a usable transcript is a transcription service that accepts TRM files directly — no conversion step required.

MatterScribe is built specifically for this workflow. Instead of exporting audio through FTR Player and then uploading to a separate transcription service, you upload the TRM file directly to MatterScribe. The platform:

• Reads the TRM format natively, including multi-channel audio and metadata
• Processes the audio through AI optimized for legal terminology
• Generates a transcript with speaker identification and timestamps
• Delivers the transcript in minutes, not days

This eliminates the most time-consuming part of working with TRM files: the export and conversion process. For attorneys and paralegals managing multiple court recordings, the time savings are substantial.

Method 4: Manual Conversion + Traditional Transcription

If you prefer a traditional transcription service, you'll need to convert the TRM file to a standard audio format first, then submit it for transcription.

Step 1: Convert TRM to MP3 or WAV

Use one of these approaches:

• FTR Player export (described above) — free but manual
• VLC Media Player — may work for some TRM files, though results are inconsistent
• FFmpeg — a command-line tool that can handle some TRM variants, but requires technical knowledge

Step 2: Submit to a transcription service

Once you have a standard audio file, you can upload it to any transcription service. Options include:

• Human transcription services (Rev, Verbit, SpeakWrite) — $1.50 to $5.00 per audio minute, 2-14 day turnaround, 98-99% accuracy
• AI transcription services (Sonix, TurboScribe, Otter.ai) — $0.05 to $0.30 per audio minute, minutes turnaround, 85-96% accuracy
• Court reporting agencies (Vernon Court Reporters, local agencies) — per-page pricing, 7-30 day turnaround, 99%+ accuracy for certified transcripts

The trade-off with this approach is time. Between the conversion process and the transcription turnaround, you may be waiting days or weeks for a transcript that you need now.

Comparing Your Options

Method	Cost	Turnaround	TRM Native?	Transcript Included?
FTR Player	Free	N/A (playback only)	Yes	No
FTR Justice Cloud	Varies	Hours to days	Yes	Optional (QuickDraft)
MatterScribe	From $25/mo	Minutes	Yes	Yes — AI with speaker ID
Manual conversion + human transcription	$1.50-$5.00/min	Days to weeks	No — requires export	Yes
Manual conversion + AI transcription	$0.05-$0.30/min	Hours	No — requires export	Yes

Tips for Working With TRM Files

Keep your original TRM files. Even after converting or transcribing, retain the original TRM files. They contain metadata and multi-channel audio that you may need later, and they serve as the authoritative source recording.

Note the channel assignments. When you receive TRM files from a court, ask the clerk which microphone channels correspond to which speakers. This information helps you (or your transcription service) produce more accurate speaker-labeled transcripts.

Check file sizes. TRM files for long proceedings can be very large — sometimes several gigabytes for a full day of court audio. Make sure your upload connection and storage can handle the file sizes before starting.

Request recordings promptly. Courts typically make FTR recordings available within hours of a proceeding, but retention policies vary. Some courts delete recordings after 30 to 90 days unless a transcript has been ordered. Don't wait to request your copies.

The Bottom Line

TRM files don't have to be a bottleneck in your legal workflow. While the proprietary format creates friction, there are now tools that handle TRM files natively and deliver transcripts in minutes rather than days.

If you're regularly working with ForTheRecord court audio, the most efficient approach is a transcription service with native TRM support — it eliminates the conversion step entirely and gets you from court recording to searchable transcript as fast as possible.
