fat_llama_fftw is a Python package for upscaling audio files to FLAC or WAV formats using advanced audio processing techniques. It utilizes fftw-accelerated calculations to enhance audio quality by upsampling and adding missing frequencies through FFT, resulting in richer and more detailed audio.
AudioSpectraCLI is a tool that provides real-time FFT visualization of audio spectra. It captures audio input from the microphone and displays the corresponding frequency spectrum directly, allowing users to monitor and analyze audio signals.
