# FM Synthesizer with HIP (ROCm and CUDA)
- Work in progress.
This project demonstrates **FM Synthesis** (Frequency Modulation) using **HIP** (Heterogeneous Compute Interface), enabling high-performance sound generation on both AMD and NVIDIA GPUs.
## Key Features
FM Synthesis:
- Implements basic **FM synthesis** to generate sounds by modulating one oscillator's frequency (carrier) using another oscillator (modulator).
- Audio data is generated and then written to a .wav file for playback or further processing.
- Supports 16, 24 and 32 -bit PCM Output at variable sample rates.
- Multiple waveforms supported: Sine, Square, Triangle, Sawtooth.
- Can read, parse and generate audio data from a MIDI file.
## Dependencies
- Ensure that your system supports HIP (either via AMD ROCm or via NVIDIA CUDA).
- Make
## Build and run
```bash
git clone --recurse-submodules git@github.com:Avicted/HIP_FM_Synthesis.git
make all
make run
```
## Program Output
The following command generates a .wav file with a 1-second sound clip using the default parameters:
```bash
./build/Main
