Portable Digital Recorders and Audio Workstations
Calculating the Space Required to Store Digital Audio
This information applies to the following Yamaha models: 01V, 01V96, 02R, 02R96, 02RV2, 03D, 03DVEK, AW16G, AW2816, AW4416, CDR1000, D24, DM1000, DM2000, DS2416, PM1D, PROMIX01.
Calculating the space needed to store digital audio on a hard disk, CD-R/RW media, or an Iomega Zip/Jaz® disk, etc., requires knowledge of the sample rate to be used, the digital word length, the number of tracks to be recorded, and the exact length of the audio file in seconds. Common values used for the sample rate are 44.1 KHz, 48 KHz and 96KHz; digital word lengths are typically 16, 20 or 24 bits; and there can be up to 64 or more tracks.
The Formula: (Sample Rate) x (Number of Tracks) x (Word Length/8) x (Song Length in Seconds)
Calculating the space needed to store digital audio on a hard disk, CD-R/RW media, or an Iomega Zip/Jaz® disk, etc., requires knowledge of the sample rate to be used, the digital word length, the number of tracks to be recorded, and the exact length of the audio file in seconds. Common values used for the sample rate are 44.1 KHz, 48 KHz and 96KHz; digital word lengths are typically 16, 20 or 24 bits; and there can be up to 64 or more tracks.
The Formula: (Sample Rate) x (Number of Tracks) x (Word Length/8) x (Song Length in Seconds)
NOTE: Since there are 8 bits in each byte, the word length, which is measured in bits, must be divided by 8 to convert the word length into bytes, a standard unit of measurement used for hard drives and other types of storage media.
EXAMPLE: A 24-bit stereo wave file song that is 2 minutes 45 seconds long and is recorded at a 44.1KHz sample rate will require 59,535,000 bytes, or 56.7 megabytes (1,048,576 bytes = 1 megabyte) of hard disk space using the calculations outlined below.

NOTE: Although it is possible to determine the space required to store digital audio, some audio recording applications may have differing space requirements for storing temporary files while the digital audio is being recorded.
