DTMF Tone Decoder 1.0

The DTMF Decoder software is an essential tool for audio technicians, police officers, forensic technicians, countermeasures technicians, and other audio related fields. The program provides the user a audio spectrum analyzer that is powerful and simple to use without complicated menus and setup requirements. If you require a complicated engineering program that costs hundreds - thousands of dollars, this is not the program for you.

The features of the software include a 2048 FFT Spectrum Analyzer, a WAV recorder / player with built in looping, a sine wave and white noise generator, a simple oscilloscope, and a DTMF decoder for decoding recorded DTMF tones from WAV files with a 45 character display window. DTMF decoding in real time from WAV files or high speed DTMF decoding from the file (faster than real time). The software uses the built in microphone / line / aux / CD inputs from your internal or external sound card. The analyzer provides the capability to store and recall audio spectrums, print spectrums, applying gain to the signal, and load saved spectrums behind active inputs.

The software features a standard WAV player with built in loop function, display of file name, sample rate, bit resolution, elapsed time, remaining time, level indicator, play, record, pause, and a high speed WAV file scan for DTMF tone decoding.
