I’m looking for a way to record (whistle & flute) and then play back without being dependent on a usb connection or headphones. I guess what I have in mind is something like the old cassette recorders. It doesn’t have to be digital. I’m not sure what I’m looking for exists anymore. I’ve searched through topic on this forum and couldn’t find anything.
I use the h4n, which has a speaker. I don’t know how long the batteries last. Hours, at least. I use NiMH rechargeable batteries, which last longer.
The problem with all of these miniature recorders is the speakers are very tiny. If you want to hear your phrasing, then they will work, but if you want to evaluate tone, you pretty much need the headphones.
