How do I convert an SPH file to OGA?

Upload your SPH file using the form above, select OGA as the output format, and click 'Convert'. Our tool processes the audio server-side, preserving original sample rate and stereo channels. Download the resulting OGA file immediately after conversion finishes. No software installation needed.

Why should I convert SPH audio to OGA?

SPH files store raw PCM audio with large uncompressed size, commonly used in speech research. OGA uses Ogg Vorbis compression, reducing file size by up to 90% while maintaining perceptible audio quality, making it ideal for web streaming, mobile apps, and platforms that support open codecs.

Does SPH to OGA conversion preserve audio quality and metadata?

Our converter decodes SPH's PCM data and re-encodes it using high-quality Vorbis at 192 kbps. Sample rate and channel count are retained, but any embedded text metadata in the SPH header is not carried over to the OGA container. For lossless archiving, choose FLAC within an Ogg container if available.
