MPEG Audio Dub

This tool, requested by Mike Eschman, copies an MPEG System Stream replacing Audio Stream 0 with an audio stream from another file. The replacement audio stream must have the same parameters as the original otherwise the timing will screw up.

Notes:

The audio stream produced by the MPEG-Cam is Layer 1, mono, 32 kHz, 128 kbps.
You can make such a file with Cool Edit 96. You will need the MPEG filters.
It's usually convenient to edit your sound at 44.1 kHz and downsample before saving.
Pad the audio file with silence if it is too short - this is not done for you.

Usage:

audiodub mpegin audioin mpegout

Source:

audiodub.c - ANSI C, uses stdio. Tested on Solaris and Win95.

Binary:

audiodub.exe - Win95 / NT 32-bit console-mode binary.

Sample Audio:

i20.mpg - First 20+ seconds of Surf Riff © 1997, Bruce Ellis. Note that this file is just an audio stream and only has the "mpg" suffix for the benefit of stupid browsers. It should be 320 065 bytes - if it hasn't been interpreted as a text file!
