Bulk upload the production
Drag in every recording from a production at once. Files process in parallel, so a batch uploaded in the afternoon is transcribed and searchable before you leave for the day.
Hours of recorded evidence, reviewed as text
Productions increasingly arrive heavy with audio and video: bodycam, surveillance-style footage, calls, and interviews. Sonix transcribes every recording at $10 per audio hour, so your team reads, searches, and quotes the evidence instead of scrubbing through it in real time.

Every recording in the production,
transcribed and searchable
Litigation teams use Sonix to review the recordings in a production. Upload the audio and video, get timestamped, speaker-labeled transcripts back in minutes, and work the recorded evidence as text.
Video evidence
Bodycam, dashcam, and surveillance-style footage becomes timestamped text, so hours of video are reviewed by reading rather than watching in real time.
Calls & audio recordings
Recorded calls, interviews, and voicemails turn into transcripts with timestamps, so the audio in a production gets the same close read as everything else in the file.
Speaker labels across recordings
Sonix separates and labels speakers automatically, so you can follow who said what in a call or interview and attribute every quote to the right person.
Search every file at once
Multi-file search runs one query across the whole production, surfacing a name, a date, or a phrase from any recording in seconds.
Timestamps on every line
Every line carries a timestamp back to the source recording, so any quote in your notes or your briefing points to the exact moment it was said.
Security that stands up to legal scrutiny
Evidence and case files demand more than promises. Every claim below is part of how Sonix runs today — and your IT or procurement team can verify all of it.
SOC 2 Type II certified
Independently audited every year against the highest standards for security, availability, and confidentiality — with continuous monitoring of 100+ internal controls.
HIPAA BAA available
Sonix signs Business Associate Agreements on Enterprise plans and implements the required safeguards — relevant for personal-injury, medical-malpractice, and health-records evidence.
No AI training on your data
Nothing you upload is ever used to train our systems — or anyone else's. Your recordings and transcripts remain strictly confidential and are never sold or shared.
Encrypted at every layer
TLS encryption for every transfer and AES-256 server-side encryption at rest — one of the strongest block ciphers available — across our database and file storage.
Role-based access & 2FA
Grant and revoke team access quickly with multiple permission levels, require two-factor authentication, and password-protect shared files.
You control your data
View, export, and delete your files at any time — deleted audio and transcripts are completely wiped. GDPR-ready, with DPA and SCC available on request.
From production received,
to evidence reviewed
A production heavy with recordings used to mean weeks of real-time listening. With Sonix the workflow inverts: the recordings are transcribed first and reviewed as text, so the team reads at its own pace, searches everything at once, and spends listening time only on the moments that actually matter.
- 1Bulk upload the recordings in the production. Drag in every audio and video file at once. Recordings process in parallel at $10 per audio hour, so a production uploaded in the afternoon is transcribed before the day ends.
- 2Verify the recordings the case will lean on. Reviewers work through the transcripts in the in-browser editor with the media playing alongside the text, confirming speaker labels and correcting what the AI misheard in the files that matter most.
- 3Work the record instead of the media. Multi-file search surfaces a name, a date, or a phrase from any recording in seconds, and every quote exports with a timestamp pointing back to the exact moment in the source file.
AI evidence review, answered directly
What does evidence review look like with AI transcripts?
Upload the recordings from a production and Sonix returns timestamped, speaker-labeled transcripts in minutes. Your team reads instead of listens, searches across every file at once, and clicks any line to hear the original moment. Review shifts from scrubbing media to working with text.
Can Sonix handle video evidence as well as audio?
Yes. Sonix transcribes video the same way it transcribes audio: bodycam, dashcam, surveillance-style footage, and recorded interviews all become timestamped transcripts. Clicking a line plays the video from that moment, so you can watch the context around any statement before relying on it.
How do I find one statement across an entire production?
Multi-file search runs a single query across every transcript at once, so a name, a phrase, or a dollar amount surfaces from any recording in seconds. Results show the surrounding text and a timestamp, and one click plays that moment in the source file.
Who verifies the accuracy of the transcripts?
Your own staff. Sonix delivers a working AI transcript, up to 99% accurate on clear audio, and your team verifies it in the in-browser editor while the recording plays alongside the text. The version you rely on is one your team has checked line by line.
What does it cost to transcribe a production?
Sonix is $10 per audio hour on the pay-as-you-go plan, with no subscription required. A production with twenty hours of recordings costs $200 to transcribe, a fraction of the staff time spent listening in real time, so teams transcribe everything instead of sampling.
Is Sonix secure enough for produced evidence?
Yes. Sonix maintains SOC 2 Type II compliance, encrypts files with AES-256 in transit and at rest, and never uses your uploads to train AI models. Permissions control who on the team can open each file, so sensitive recordings stay with the people assigned to the matter.
