    What format does the 3DS audio recording use? I want to add in my own sounds since recording it is bad quality. I'll be using it for swapnote.

    I am able to insert clear audio tracks using a different method that does not involve taking the SD card out

    Is there like a specific requirement I must follow, like for videos? Or can I just put in any mp3 and it'll work.

    @Randamin: How? :blink:

    within the 3ds itself I think the videos are limited to 10 minutes, not sure of video format but there are various threads here for converting video.

    An audio adapter that separates the audio and mic from the single headset jack in the 3DS.

    After that
    1. Connect an audio cable from your audio source to the mic socket on that adapter
    2. Set the audio levels to optimal position
    3. Start recording (remember no more than 5 seconds for swapnote)
    4. ...
    5. PROFIT!

    he meant to say that does the audio file have to be encoded in a specific way the same way videos also need special encoding to be recognized by the 3DS gallery app.

    If you prefer to have something to mess around with for now:
    I checked my SD card and was able to find the location where the voice clips from 3DS sound are stored. It may not be the exact same directory but this should point in the right direction
    sd_card_root:\Nintendo 3DS\Private\00020500\voice\01\V12111.m4a

    As seen here the files are encoded in AAC format at a bitrate of 32kbps with a sample rate of 32000 Hz. To be safe its best to avoid deviating too much from this format. I know iTunes has a creat AAC format option but am not sure how to set the bitrate and sample rate right now.

    That's mad spendy for such a simple cable.
