Supports: VOC
The Creative Voice (.voc) container was introduced in 1990 alongside Creative Labs' Sound Blaster sound cards and dominated DOS-era game audio for roughly a decade. It uses block-based PCM (originally unsigned 8-bit, later 16-bit, with optional 4/3/2-bit ADPCM and A-law / mu-law variants) and a 26-byte header followed by typed data blocks. Outside of retro emulation and a handful of legacy digital voice recorders, almost nothing plays VOC natively in 2026 — Windows dropped Sound Blaster's mixer decades ago and modern phones, browsers, and DAWs expect WAV, MP3, AAC, or FLAC.
<audio> elements in Chrome, Firefox, Edge, and Safari play MP3 natively; VOC has no MIME-typed browser support.| Property | VOC (Creative Voice) | MP3 (MPEG-1 Audio Layer III) |
|---|---|---|
| Year introduced | 1990 (Sound Blaster era) | 1993 (ISO/IEC 11172-3) |
| Compression | Mostly uncompressed PCM; optional ADPCM / A-law / mu-law blocks | Perceptual (lossy) |
| Typical bit depth | 8-bit (original), 16-bit (extended) | n/a (encoded bitstream) |
| Typical bitrate | ~64-352 kbps depending on rate and bit depth | 32-320 kbps (CBR), VBR also common |
| Native player support 2026 | Almost none — VLC, ffmpeg-based tools, retro emulators | Every browser, OS, phone, car stereo, DAW |
| Best use | DOS-era game audio, vintage Sound Blaster recordings | Universal playback, podcasts, music, voice memos |
| File size (30 min mono) | ~40 MB at 8-bit 22 kHz | ~27 MB at 128 kbps |
| Bitrate | Best for | Notes |
|---|---|---|
| 64-96 kbps | Speech, audiobooks, dictation | Adequate for voice; audible artifacts on music |
| 128 kbps | Everyday playback, podcasts | The historical "standard" MP3 quality |
| 192 kbps | Music streaming, mixed content | Most listeners can't distinguish from 320 in a blind test |
| 256-320 kbps | Music archives, "near-CD" target | Largest files; smallest perceptual loss |
| VBR 170-210k (MP3) | Music with quiet and loud passages | Allocates bits where needed; smaller average size |
Because the Creative Voice container is essentially abandoned outside niche retro tools. Windows hasn't shipped a built-in VOC decoder since the late 1990s, and iOS/Android media frameworks don't recognise the magic bytes "Creative Voice File\x1A". VLC and ffmpeg-based tools (including this converter) still decode VOC correctly via libavformat, then re-encode to MP3, which every device handles.
Mathematically yes — MP3 is lossy, VOC's PCM blocks are not. In practice, original VOC content is typically 8-bit at 11-22 kHz (designed for 1990s Sound Blaster DACs), which already has lower dynamic range and bandwidth than CD audio. Encoding that to 192 kbps MP3 is overkill from a fidelity standpoint and effectively transparent. If you want a lossless target instead, use VOC to FLAC or VOC to WAV.
128 kbps is fine for the great majority of DOS-era VOC content (mono, 8-bit source, short SFX or speech). Bump to 192 kbps if the source happens to be a 16-bit Sound Blaster 16 / AWE32 recording with music, or if you're archiving for YouTube uploads where the platform re-encodes. Anything above 256 kbps is wasted bits on 8-bit source material.
VOC stores sample rate as 256 - (1000000 / rate) in a single byte, which can wrap or be misread on unusual rates. Some older rippers also embed nonstandard rates that ffmpeg interprets at the wrong speed. Try re-uploading and setting Audio Sample Rate explicitly (8000, 11025, 22050, or 44100 Hz) to match what the original Sound Blaster played back. If the source was 8-bit unsigned and you hear DC offset clicks, that's the format, not the conversion.
Yes. VOC supports several Creative ADPCM variants (4-bit, 3-bit, 2.6-bit) plus A-law and mu-law block types. Our decoder handles the common variants from Sound Blaster Pro and SB16 era files. If a specific file fails, it's almost always a malformed block, not the codec.
Free uploads run up to several hundred MB per file, which is far larger than any real Creative Voice recording (the format was rarely used past a few minutes per clip). If you're working with a long rip — a full game's voice archive concatenated — split it first or use the Trim controls to extract a section.
Both are containers around PCM audio, but WAV (RIFF WAVE, Microsoft / IBM, 1991) became the Windows standard and is supported everywhere; VOC stayed tied to Creative's hardware and faded with the rise of AC'97. WAV uses chunked RIFF structure, supports far more codec extensions (including PCM, ADPCM, GSM, MP3-in-WAV), and has consistent sample-rate fields. If you need a lossless modern target, VOC to WAV is the direct route.
Yes. Uploads are processed for your conversion and removed from our servers shortly afterward — we don't catalog content, sell metadata, or require an account. If you'd rather compress an existing MP3 further (for email or Discord's 10 MB free-tier limit), the dedicated MP3 compressor is faster than re-running a VOC conversion.
