Hello friends, I want to purchase the music player of the SanDisk, but I need to be familiar with the specification on the radio record function. I want to ask that in which file format does it record (.wav, mp3) and also at what bitrates does it record? (96kbs, 128kbs, 256kbs) and also How is the recording sound when played back? So guys please answers to the question as it will help me to purchase it. Thank you.
