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.

Hi there, A sample result will be provided before awarding the project. I can help restore your recordings by targeting the high-frequency beeps and squeals while preserving the natural quality of the speech. Given the variation in source devices and recording conditions, I would first analyze a sample file and build an appropriate noise-reduction workflow that minimizes artifacts and maintains intelligibility across the entire archive. The process can include high-frequency noise suppression, speech enhancement, volume balancing, and clarity optimization while preserving the original file format and sample rate requirements. Once the sample is approved, the remaining recordings can be processed in organized batches to ensure consistent quality throughout all 50 hours of material. I can also assist with the transcription stage and provide time-stamped transcripts if required. Please send a sample recording and I’ll evaluate it before confirming the best approach and estimated turnaround for the full archive. Thanks!

As someone whose day job is live sound engineer, removing annoying beeps and squeals is my absolute specialty. I'd be utilising parametric sweeps using a thin bandwidth to remove noises, then identifying which bandwidth(s) the noises you want to keep reside in and boosting them - I do this almost every day and have done for the over 20 years I've been a sound engineer. I'm used to doing this on the fly using digtal desks, in live situations where working fast is of the utmost importance. Doing it as a recording engineer after training in this manner is second nature to me, and I use this technique every time I mix and master recordings in my studio. The transcription would be no issue either. Would love to get my hands on the test sample to show you what I can do.
