About PCM files
PCM (Pulse Code Modulation) is the standard digital audio format that represents sound waves as numerical values. It's uncompressed, maintaining perfect audio quality but creating large file sizes. PCM serves as the basis for formats like WAV and CD audio, widely used in professional recording and broadcasting. Though not space-efficient, its lossless nature makes it ideal for high-fidelity audio applications where quality preservation is crucial.
About OPUS files
Opus is a versatile, open-source audio codec developed by the IETF, combining the strengths of both speech and music compression. It delivers high-quality sound at very low bitrates, making it ideal for VoIP, streaming, and real-time communication. Opus excels in dynamic bitrate adjustment and works well across a wide range of applications, from low-latency gaming chats to high-fidelity music streaming. Supported by most modern browsers, devices, and platforms, it has become a key format for internet audio.
