Audacity 3.2 … whatever Mac OS is new in 2015. Obtained the Audacity .dmg installer.
I did a bunch of stupid things. I was recording a podcast using a Zoom H5 Handy Recorder and an SD card. The card got full so I went to move my files into my Dropbox, but they accidentally ended up in my trash. They then deleted immediately from my trash without a prompt. After consulting with Apple help, they concluded that if I were to recover the files, they’d be on the card’s ‘trash’ and not my MacBook Air’s trash.
Someone then formatted the card. We then recorded over the card. The files were gone.
But! I downloaded recovery software and was able to locate the .wav files. Unfortunately, the files are openable, but they include defects like loud “fuzz” or gaps at regular intervals (which seems more fixable? all of the audio is there, it’s just the gaps). I’ve been reading about this hack wherein you import the raw file: https://forum.audacityteam.org/t/corrupt-zoom-h4n-file/19841/1
But I don’t know how to adjust the settings to make it sound right. Is there anything that can be done??
