    Roughly how many tracks (or songs tho some will be solo piano and others will be vocals plus 3 or 4 instruments) can you record onto an 8 GB sdhc card?
    Thanks ahead for any input!

    To answer that, there are too many variables. Are you recording 16 or 24 bit files, 44.1, 48 or 96 kHz sample rate files? Some examples:
    1 min of mono audio @ 16 bits and 44.1 kHz results roughly in a 5 MB file.
    1 min of mono audio @ 24 bits and 44.1 kHz results roughly in a 7.6 MB file.
    1 min of mono audio @ 24 bits and 48 kHz results roughly in a 8.2 MB file.
    1 min of mono audio @ 24 bits and 96 kHz results roughly in a 16.5 MB file.

    To calculate: bit depth x sample rate x 60 / 1024 / 1024 / 8 x 60 is your file size in MB for 1 minute per mono track.

    Thanks Arjan!
    I am using the Dp-03sd. So recording is 16 bit/44.1 kHz
    Just wanted to get an idea before getting a sd card of what to expect.
    I went ahead and ordered a 32 GB card (class 10)
    A lot of tracks will be stereo....some solo instrumental mono

    32 GB should give you more than enough capacity. From the above examples, a stereo track takes simply twice as much space. So a 5 minute song with 10 tracks (where stereo counts for two) would be 250 MB. One quarter GB ;). Have fun filling up that card!

    That sounds good, thank you Arjan P!
