How do I convert a GSM file to OGA?

Why should I convert GSM to OGA?

GSM files are optimized for mobile phone voice calls with a low 8kHz sample rate and 13kbps bitrate, making them sound narrow. OGA files use the Vorbis codec, which supports up to 48kHz and variable bitrates, resulting in richer, clearer audio for music, podcasts, and modern media players. Converting improves compatibility and audio fidelity.

Does GSM to OGA conversion preserve the original audio quality?

When converting, the GSM stream is decoded to raw PCM and then encoded into OGA/Vorbis. Since GSM is a lossy format, the output cannot recover frequencies above 4kHz or the original dynamic range, but the OGA file will be re-encoded at your chosen bitrate (default 128kbps). No additional data is invented; the process maintains the inherent spectral characteristics of the source while improving container compatibility.
