I have several interview recordings where the participants drop their voices to a near-whisper right at the moments that matter most. I need those low-level passages isolated, enhanced and then transcribed accurately into clear, well-formatted text.

I typically work with WAV and MP3 files; if you prefer a different format, let me know before we start so I can convert them for you.

High-quality restoration with no metallic artifac...
