I've been frustrated with clipping in my recordings using my Zoom H4n pro. Most of my recordings are improvisations and I don't know ahead of time how loud I'm going to play. I've struggled with getting the gain right.
I read about 32 bit float audio on PW a few months ago and was intrigued. After some of my recent recordings suffered from clipping, I ordered a Zoom H1essential. Today I made a test recording with as much dynamic range as I could and then worked through the process of creating a video for YouTube without clipping.
I use iMovie to combine the audio from the recorder with the video from my phone. With the H1essential recording I don't hear any clipping on playback in iMovie, even though the peaks in the audio look too high. If I export to .mp4 with the default output level and play it back, there is clipping. Unfortunately this means trial and error to find the right output level to set in iMovie. But it works! I may need to investigate a better tool for making videos.
I've been using GarageBand to make audio files for PW recitals. So far I haven't figured out a way to convert my test recording from 32 bit float to 24 bit without audible clipping using GarageBand. I installed Audacity today and I'm hoping I can make that work.
My conclusion so far is that 32 bit float audio is harder to work with than 24 bit audio, at least with the tools I've been using. It's worth it though to be able to share recordings that aren't clipped!
