Understanding WAV and FLAC file formats

WAV (Waveform Audio File Format) is a standard audio file format used for storing waveform data. It is commonly used for high-quality audio files and is known for its lossless audio quality, meaning it retains all the original audio data without compression.

FLAC (Free Lossless Audio Codec) is an audio format similar to WAV in that it is also lossless, but it uses compression to reduce file size without losing any audio quality. This makes FLAC a popular choice for audiophiles who want to save space while maintaining high audio fidelity.

How to convert WAV to FLAC

Converting WAV files to FLAC can be beneficial if you want to save storage space while keeping the audio quality intact. Here are the steps to convert WAV to FLAC:
