VOC is the Creative Labs Voice format from the Sound Blaster era. Reaching a SND from there is one hop. Turn your VOC audio into a widely-supported SND file. The conversion happens server-side through FFmpeg — the same engine behind every major audio editor — so the output plays cleanly on phones, car stereos, DJ software and streaming tools. Technical note: VOC is the Creative Labs Voice format from the Sound Blaster era. Compare that with SND is an audio format with specific trade-offs between file size, bitrate flexibility, and device support.
Creative Voice
Source formatVOC (Creative Voice) is an audio file format created by Creative Labs for Sound Blaster sound cards. It was a dominant PC audio format in the DOS gaming era, supporting multiple data blocks with different sample rates within a single file.
NeXT Sound
Target formatSND (NeXT Sound) is an audio file format originating from NeXT computers and later adopted by Sun Microsystems as the AU format. It stores audio with a simple header and supports various encodings from 8-bit mu-law to 32-bit floating point.
Why convert VOC to SND
The motivation for a VOC → SND conversion is almost always practical: a playback device, hosting platform or editing suite that insists on SND. The audio quality trade-off is controllable via bitrate; the compatibility win is immediate and unambiguous.
HOW TO CONVERT
VOC → SND
Give us the VOC
Select a VOC (or several for batch). We read the header to pick decoder settings automatically.
Re-encode to SND
The audio is decoded, optionally resampled, and re-encoded as SND at transparent default bitrate.

Common Use Cases
Cross-platform music libraries
Moving libraries between iTunes, foobar2000 and Plex is smoother when tracks are standardised on SND.
Streaming uploads
SoundCloud, Bandcamp and YouTube Music accept SND directly; VOC triggers a transcoding step and a delay.
Legacy hardware playback
Older car head units, portable players and boomboxes often decode SND exclusively — a lasting compatibility guarantee.
Ringtones and notifications
iOS, Android and Windows all accept SND as a system sound or custom ringtone with no further conversion.
Quality & Compatibility
The SND output is as good as the VOC source allows. If the VOC was encoded at 96 kbps, the SND cannot reconstruct detail the encoder already dropped; picking a very high SND bitrate just produces a larger file. Match SND bitrate to the VOC quality for the best balance.
Tips for Best Results
- Sample-rate mismatches between VOC and target device (48 kHz phone output from a 44.1 kHz track) are handled automatically; no manual resampling needed.
- For audiobook delivery, match the platform spec exactly — ACX requires 192 kbps CBR 44.1 kHz stereo, for example.
- Batch-convert an album in one job so every track shares identical encoder settings and loudness normalisation.
Frequently Asked Questions
Frequently Asked Questions
Lossy-to-lossy conversions (most combinations) re-compress the audio, which technically introduces some loss. At a 192 kbps or higher target it is inaudible on normal equipment. Lossy-to-lossless conversions freeze the existing quality but cannot improve it; lossless-to-lossy transcodes are only as good as the target bitrate you choose.
For voice content (podcasts, audiobooks, lectures) 128 kbps is indistinguishable from higher bitrates. For music, 192-256 kbps covers most listening; 320 kbps is the ceiling for SND and the right choice for audio you plan to edit further. Above that, prefer a lossless target instead.
Yes. Title, artist, album, year and cover art travel from the VOC container to the SND container automatically where both formats support them. If a tag field has no SND equivalent, it is dropped silently. Use any tag editor (Mp3tag, MusicBrainz Picard) to fine-tune afterwards.
