Audio Latency Calculator: Buffer Size to Milliseconds
See how much delay a buffer size adds at each sample rate, and how much disk space a recording takes at a given sample rate, bit depth and track count.
Recording file size
How it works
One buffer takes buffer size ÷ sample rate seconds to fill, so 256 samples at 48,000 Hz is 5.3 ms. Your computer buffers the input and the output, so the round trip is at least twice that. Converters and drivers add a little more on top, and that extra part depends on the interface, so check the latency figure your recording software reports for the real total.
Uncompressed audio (WAV or AIFF) takes sample rate × bit depth ÷ 8 bytes per second for each track. The size above uses the sample rate chosen in the latency tool. 1 GB here means 1,000,000,000 bytes.
