How do I convert an OGA file to SPH?

Step 1: Select your OGA file. Step 2: Choose SPH (SPHERE) as the target format. Step 3: Adjust sample rate and bit depth if needed (defaults match the source). Step 4: Click 'Convert' and download your .sph file. The entire process completes in seconds.

Why should I convert OGA to SPH instead of keeping it as OGA?

OGA (Ogg Vorbis) is a compressed, lossy format that reduces file size but loses audio fidelity. SPH (NIST Sphere) stores uncompressed PCM audio, preserving the exact waveform. Speech recognition software, linguistic analysis tools, and research databases often require SPH files. While SPH files are much larger, they guarantee lossless, high-fidelity audio for critical processing.

How does the OGA to SPH conversion handle audio quality like sample rate and bit depth?

When you convert OGA to SPH, the audio is decoded to uncompressed PCM. The sample rate and bit depth are preserved exactly from the source file (e.g., 44.1 kHz/16-bit remains 44.1 kHz/16-bit). However, because OGA is lossy, the resulting SPH file cannot restore frequencies lost during original OGA encoding—it contains the exact decoded audio data, no more and no less.
