Hi all,
I am doing a research project that involves interviewing people using the Voice Memo app on my iPhone and then transcribing their interviews. For one of my interviews, I accidentally left my Bluetooth headphones connected, and the recording reverted to using the headphone mic (which I had stuck in a drawer). As a result, the audio quality is pretty poor, and I am having trouble producing an accurate transcription from the recording. The quality problems seem two-fold:
- a pronounced hissing noise that continues throughout the recording.
- a muffled quality to the vocals, especially for my interviewee (who was seated farther away from the headphones drawer than I was.)
I wish I could post sample audio, but because I need to maintain research confidentiality, I cannot. I tried applying noise reduction, and that reduced the hissing noise some, but not enough to make my interviewee’s words legible. The recording does not have to sound great by any means, just good enough that I can make out the words.
Does anyone have suggestions for ways to improve this audio file? Thanks in advance!
I am running Audacity 2.3.0 on a Windows 10 Enterprise machine.
