I have an MP3 call recording and need each speaker isolated into its own clean track. The source is a standard phone call, so there are at least two distinct voices overlapping at times. My priority is accurate multi-voice extraction; simple background noise reduction is welcome if it improves clarity, but the core task is to split the voices so they can be edited individually. Please let me know the tools or workflow you prefer (iZotope RX, Adobe Audition, Python-based diarization, etc.) and the turn-around time you can commit to. Final deliverables should be separate audio files for every detected speaker, exported in WAV or high-quality MP3, along with a brief note on the method used so I can replicate adjustments later if needed.
