Audio Forensics: Enhancement, Identification, Reduction

I have a project requiring the expertise of a forensic audio specialist. The crucial tasks include:

- Enhancing the quality of the sound,
- Identifying voices in the audio,
- Reducing the noise to extract critical information from the recording.

The original format of the audio files is WAV, which should be preserved during the processing phase. Also, please provide a written transcript of only the key conversations extracted from the enhanced audio. For this task, proficiency in audio forensic software, experience with the WAV format, and excellent transcription skills are ideal.
