Piezo Speaker Ringtones

I'm looking for someone who is capable of converting a .WAV file to the approriate Arduino code to let it ring with a Piezo ringtone. These ringtones will be used for an electronic device with piezo speaker, in which we are capable of producing audio between the 3.5Khz and 4.5 Khz frequencies. This of course means that the ringtone via the piezo speaker will not sound the same as the original .WAV file, however the type of tune needs to remain the same. The project has a quick turn-around time, so it's important to find a reliable Freelancer able to work on a short timeline. Experience in sound engineering or audio production is a must.

I've tried it myself using these steps:

1. Create the Wav file.
2. Analyze of WAV file. Using WAVE and NUMPY.
3. Then export frequencies and durations. Using WAVE, NUMPY, and LIBROSA
4. Reiterate exported frequencies and durations in normal lists
5. Convert tones to tones between 3.5khz and 4.5khz.
6. Convert all output to workable Arduino code.

It all succeeded but the output of audio is not workable (high pitching not similar to the tune I gave as input at all). Who can help make it right?



But the output I get is unusable.
