Clean & Transcribe Noisy Recordings

I have around 50 hours of voice recordings that are buried under persistent high-frequency beeps and squeals. My priority is to strip out that piercing layer, bring the speech forward, and deliver files that sound natural enough to review comfortably. If you can also produce an accurate text transcription once the audio is restored, that’s a welcome bonus. The source material is a mix of MP3 and MP4 files and was captured on different devices, so noise levels vary from clip to clip. I need a consistent workflow that: • isolates and suppresses the high-frequency noise without introducing artifacts, • balances and boosts spoken words for clarity, • exports the cleaned tracks in the same file type and sample rate I provide, • (optional) delivers a verbatim transcript time-stamped every minute. I’m happy to supply a short sample first so you can demonstrate your approach—tools such as iZotope RX, Adobe Audition, or equivalent DSP plugins are fine as long as the result is crisp, intelligible speech. Once the method is approved, the full batch can be processed in manageable batches. Let me know how soon you can turn around the sample, the estimated time for the entire 50-hour archive, and whether you can handle the transcription stage as well.
