Audio Cleanup for Legal Use

I need a .wav audio file cleaned up and amplified for court use. The recording needs to retain original timing and speech order. Recorded time on the file is approximately 3 hours but there is quite a bit of silence that can be removed. Key requirements: - Clarify muffled voices - Reduce background noise - Maintain original timing and order Ideal skills and experience: - Proficiency in audio editing software (e.g., Audacity, Adobe Audition) - Experience with legal audio requirements - Attention to detail and accuracy
