+<h1>Audio input plugin</h1>
+
+<h2>Introduction</h2>
+
+This input sample source plugin gets its samples from an audio device.
+
+<h2>Interface</h2>
+
+![Audio input plugin GUI](../../../doc/img/AudioInput_plugin.png)
+
+<h3>1: Start/Stop</h3>
+
+Device start / stop button.
+
+  - Blue triangle icon: device is ready and can be started
+  - Green square icon: device is running and can be stopped
+  - Magenta (or pink) square icon: an error occurred. In the case the device was accidentally disconnected you may click on the icon, plug back in and start again.
+
+<h3>2: Device</h3>
+
+The audio device to use.
+
+<h3>3: Refresh devices<h3>
+
+Refresh the list of audio devices.
+
+<h3>4: Audio sample rate</h3>
+
+Audio sample rate in Hz (Sa/s).
+
+<h3>5: Decimation</h3>
+
+A decimation factor to apply to the audio data. The baseband sample rate will be the audio sample, divided by this decimation factor.
+
+<h3>6: Volume</h3>
+
+A control to set the input volume. This is not supported by all input audio devices.
+
+<h3>7: Channel Map</h3>
+
+This controls how the left and right stereo audio channels map on to the IQ channels.
+
+* I=L, Q=0 - The left audio channel is driven to the I channel. The Q channel is set to 0.
+* I=R, Q=0 - The right audio channel is driven to the I channel. The Q channel is set to 0.
+* I=L, Q=R - The left audio channel is driven to the I channel. The right audio channel is driven to the Q channel.
+* I=R, Q=L - The right audio channel is driven to the I channel. The left audio channel is driven to the Q channel.
