In edwbaker/SonicScrewdriveR: Bioacoustic Analysis and Publication Tools

Calculated size of raw audio files

Description

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"

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".

Value

The size of the audio file in the specified unit

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")

# 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")
