Shared recording server

erec is a tool program for recording raw audio stream from the soundcard. Multiple instances of erec can be running at the same time sharing the same audio device. It works as a frontend to the audio device for programs wishing to listen at the same time.

erec - shared recording server v2.2.0.1 (C) 1992,2002 Bisqwit

Allows multiple applications request recorded data
at the same time with different stream attributes.
Usage: erec [<options> [...]]
Options:
    -2, --stereo         Specifies stereo sound. Default is mono.
    -6, --word           16-bit mode. Redundant.
    -V, --version        Version information
    -b, --byte           8-bit mode. Normally 16-bit mode.
    -d, --device <file>  Specify device.
    -h, --help           Help
    -m, --mono           Redundant. It's here for esd compatibility.
    -r, --rate <num>     Specifies recording rate. 44100 is default.

Note: For best quality, it might be wise to always record 44.1 kHz 16-bit stereo (-6r44100) and resample the result with an external program like resample to produce the wanted sample rate.

erec has been written by Joel Yliluoma, a.k.a. Bisqwit,
and is distributed under the terms of the General Public License (GPL).

GNU make is probably required.
A sound card (OSS) might prove useful.

Since version 2.2.0, esdcat functionality no longer exists in erec.
In 2.2.0, removed the 1sec latency between erec start and start of recording.

erec uses tcp connections between the server (first launched erec by server) and client (all listeners). The ports are calculated from the device filename by a magic formula, which results in these ports for these examples: /dev/dsp: 6130, /dev/dsp1: 6179
