Purpose</H2><div class="level2">

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.

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 &lt;file&gt;  Specify device.
    -h, --help           Help
    -m, --mono           Redundant. It's here for esd compatibility.
    -r, --rate &lt;num&gt;     Specifies recording rate. 44100 is default.

</pre>

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
<a href="http://oktober.stc.cx/source/streamixer.html">resample</a> to produce the wanted sample rate.

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

</div><H2 class="level2"><a name="h3"></a>4. Changes</H2><div class="level2">

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

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: <code>/dev/dsp</code>: 6130, <code>/dev/dsp1</code>: 6179
