Calculated size of raw audio files — audio_filesize • sonicscrewdriver

Calculates the raw size of audio date at set sample rate, bit depth and duration.

Usage

audio_filesize(
  samp.rate = 44100,
  bit.depth = 16,
  channels = 1,
  duration = 1,
  duration.unit = "seconds",
  output.unit = "bits"
)

Arguments

samp.rate: Sample rate
bit.depth: Bit depth
channels: The number of audio channels
duration: Duration of recording
duration.unit: One of seconds, minutes, hours, days
output.unit: "human", "bits" or "bytes"

Value

The size of the audio file in the specified unit

Details

By default humanBytes() is used to convert the output to human readable format, however this can be changed by setting output.unit to "bits" or "bytes".

Examples

# One minute of mono 16-bit audio sampled at 44.1kHz
audio_filesize(samp.rate=44100, bit.depth=16, channels=1, duration=1, duration.unit="minutes")
#> [1] 42336000

# One year of stereo 24-bit audio sampled at 96kHz
audio_filesize(samp.rate=96000, bit.depth=24, channels=2, duration=1, duration.unit="years")
#> [1] 1.453179e+14
