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. ON-DEVICE AUDIO WORKFLOW Models required for speech processing and multilingual transcription are included in the app. Every feature in REDREC also works offline. Supported languages: English, 한국어, 日本語, 中文, Español, Français, Deutsch, Português, Italiano, Nederlands, Русский, Українська, Polski, Čeština, Svenska, Norsk, Dansk, Suomi, Türkçe, العربية, עברית, हिन्दी, Bahasa Indonesia, Bahasa Melayu, Tiếng Việt, ไทย, Ελληνικά, Română, Magyar, Català + 69 more languages REDREC combines multiple on-device AI technologies for voice cleanup, voice/background separation, silence detection, speaker identification, and multilingual transcription. Recordings and user data—including transcripts, speaker information, and edits—are never sent to external servers. All processing is completed locally on your device. • No account required • No separate model downloads • Recordings and transcripts are not uploaded to an external server • Audio processing and transcription run on your device • Recordings, transcripts, and edits stay on your device Use REDREC for meetings, interviews, lectures, ideas, and field conversations that need to be heard and organized again. Processing speed depends on device performance and recording length. Transcription and speaker separation accuracy may vary with recording quality, background noise, overlapping speech, language, and pronunciation. Results can be corrected in the app. Record once. Focus on what matters.

Verdict
