REDREC - Offline Transcription

One recording. Five audio results. Two ways to read the transcript.

REDREC preserves the original recording, then prepares purpose-built audio results and transcripts so listening, reading, editing, and sharing stay in one clear flow.

FIVE AUDIO RESULTS

• Original
The untouched reference recording.

• Clean Voice
Reduces background noise and makes speech clearer.

• Isolated Voice
Separates speech from the background, then enhances the isolated voice.

• Silence Removed
Uses cleaned speech and removes long silences and non-speech sections for faster review.

• Background
Lets you listen to the separated background layer on its own.

ONE TRANSCRIPT, TWO VIEWS

• Text
Read the complete transcript as one continuous document. Edit or copy it quickly.

• Speakers
Review the conversation as speaker-separated turns with names, colors, and timestamps. See who said what and when.

Tap a sentence to play only its matching audio segment. Rename and recolor speakers, listen to one speaker, or mute several speakers at once. Muted segments are skipped during full playback.

Copy the full transcript or only one speaker’s text. Share the audio clip that matches a selected sentence.

EDIT WITH PRECISION

• Trim by dragging start and end positions on the waveform
• Quickly edit transcript text
• Split a transcript segment by time and text when two speakers were grouped together
• Rename recordings and speakers, and customize speaker colors
• Change playback speed and seek directly on the waveform
• Share the audio result or transcript you need

RELIABLE PROCESSING AFTER RECORDING

When you complete a recording, REDREC saves the original first and processes the remaining results in a stable sequence. If processing is interrupted, unfinished work resumes from the saved original.

Archive lets you compare Original, Clean Voice, Isolated Voice, Silence Removed, and Background in one place. After trimming, REDREC rebuilds the required results from the selected range.
