NEED URGENT HELP about 'AMR Narrow-Band Content' format watch

    • Thread Starter

    I have a Sony ericsson W700 and I use its audio recording feature which records in 'AMR Narrow-Band Content' format. I'm not much a techy person but I do know that it uses remarkably small amounts of space.

    I want to know how do I get it to play in the WALKMAN feature of the phone. It doesn;t seem to work from what I've tried after putting it into the 'music' folder along with my other MP3 songs. Anyway my whole point in trying to get it to play in the WALKMAN feature of my phone is that so I could rewind to a certain point.

    I'm guessing I need to somehow convert this into a compatible format (e.g. MP3), but wouldn't that make my audio file take up more space? because aren't MP3 higher quality? and I don't really want it to take up large amounts of space as I only have 256mb of memory in the phone.

    Even if you did convert AMR to mp3, the file size wouldn't be too much. a 3min song at 128kbps, 44.1KHz is about 3MB. The audio bitrate and sampling frequency can be reduced, infact, I highly doubt AMR uses anything close to 128kbps and 44.1KHz.
