Android - DTMF decoder algorithm.
Бюджет $250-750 USD
Create an DTMF decoder algorithm.
The Android APP should uses the algorithm to decode any DTMF tone on the audio signal received by the microphone.
The final delivery should be a Android APP that:
- Listen the microphone sound, searching for a DTMF tone.
- Decode the received DTMF tone.
- If there is a DTMF tone on the audio input then the app should display the decoded DTMF numbers.
- The software should filter the input microphone audio (digital band pass filter) to avoid noise or contaminations.
- The DTMF decoder algorithm should allow tone frequency value modification
- There is an example on Github "pjasiun/ dtmf-decoder"
