The above applet uses the best quality (a sampling rate of 44100Hz) for highly compressed audio recording, which may require a fast machine to process the recording.

If you have encountered problem such as delay or noisy playback you may try the following applets that use smaller sampling rates. The sampling rate of the NanoGong applet can be adjusted using the sampling rate parameter.

Good Quality

This applet uses a sampling rate of 32000Hz.

The above applet can be created using the following html page:

<html> <body> <applet id="applet" archive="nanogong.jar" code="gong.NanoGong" width="180" height="40"> <param name="SamplingRate" value="32000" /> </applet> </body> </html>

Average Quality

This applet uses a sampling rate of 16000Hz.

The above applet can be created using the following html page:

<html> <body> <applet id="applet" archive="nanogong.jar" code="gong.NanoGong" width="180" height="40"> <param name="SamplingRate" value="16000" /> </applet> </body> </html>
