Re: Odp: [Nature Recordists] card speed?

If you have a look at this page on the Sound Devices site about card storage & 
speed requirements, you can calculate your needed speed based on bit depth & 
sample rate.

For example I record at 24/96 and the results for me to record 60 minutes of 
24/96 in BWF format are as follows. The info you're after is the Data Rate of 
562.52 KB/Sec

***************************************************************
Results

    * Storage Space Required - 1977.6 MB (1.93 GB)

      This is the approximate amount of disk space 60 minutes of 2 track 
uncompressed WAV audio requires at 96 k / 24 bits.
    * Data Rate - 32.96 MB/minute (562.52 KB/second)

      This is the total data rate of 2 track uncompressed WAV audio at 96 k / 
24 bits.
    * DVD-RAM disks - 1

      The amount of DVD-RAM disks that 60 minutes of 2 track uncompressed WAV 
audio requires at 96 k / 24 bits
