A:AnswerAutomatically saves the recording. I have never had the battery run out in the middle of the recording so I cannot be 100% on that part of your question.
A:AnswerAbsolutely. Depending on your state or countries laws you can record phone conversations. Some allow recording as long as one party is a participant in the recording. Some only allow recording if both parties give consent.
A:AnswerOn this device, no. You can use 3rd party conversion software you might be able to.
Dictation software or possibly an app for your Android or IOS device.
A:AnswerI wouldn’t recommend using this to record music. If you want clear crisp recordings I’d aim for equipment centered more in that area. If you’re just jamming and the sound doesn’t have to be professional sounding then this would do just fine. Quality for this is still really good but it’s best when recording yourself taking notes or meetings/lectures/interviews.
