Settings

The codec to encode the audio track. Codec "Without reencoding" copies the audio stream from the input file into output without re-encoding if possible.
Set the number of audio channels. This setting is most useful when downmixing channels (e.g., from 5.1 to stereo).
Set the sample rate of the audio. Music with a full spectrum (20 Hz — 20 kHz) requires values not lower than 44.1 kHz to achieve transparency. More info can be found on the wiki.

pvf

PVF (Portable Voice Format) is a simple audio file format designed for voice message storage in Linux-based telephony systems, most notably ISDN4Linux and its vbox voicemail application. The format emerged from the European ISDN ecosystem of the late 1990s, when Linux servers increasingly handled PBX and answering machine duties over digital phone lines. PVF files store raw signed 16-bit PCM samples at 8000 Hz mono, preceded by a minimal plain-text header specifying data format and byte ordering. This deliberate simplicity is one of the format's primary strengths — with no compression and a human-readable header, PVF files are trivially easy to parse, pipe, and manipulate using standard Unix tools. The 8 kHz rate matches the Nyquist requirement for telephone-bandwidth speech (300-3400 Hz), making PVF a natural intermediate format for voice processing pipelines. Another advantage is cross-architecture portability: the explicit byte-order declaration means PVF files move between big-endian and little-endian systems without ambiguity. The SoX audio toolkit provides native PVF read/write support, enabling straightforward conversion to modern formats.

oga

OGA is the audio-only file extension within the Ogg container framework maintained by the Xiph.Org Foundation. While .ogg traditionally served as a catch-all extension for any Ogg-encapsulated stream, the introduction of .oga in 2007 brought clarity by explicitly signaling that a file contains only audio data. Under the hood, OGA files can carry audio encoded with Vorbis, FLAC, Speex, or Opus — the container is codec-agnostic, serving as a transport wrapper with support for chained logical bitstreams and granule-based seeking. One benefit of OGA is interoperability: applications that encounter the .oga extension can optimize for audio-only playback without probing for video tracks, resulting in faster load times and lower memory usage. Because the Ogg container and its associated codecs are entirely open-source and royalty-free, OGA avoids the patent licensing complexities that affect proprietary formats. The format supports Vorbis comment metadata for tagging artist, album, and track information in a standardized way. OGA plays natively in Firefox, Chromium-based browsers, VLC, and most Linux desktop environments, making it a practical choice for web audio distribution and archival workflows.

Frequently Asked Questions

Why convert PVF to OGA?

PVF is a niche telephony voice format. OGA gives your voice recordings broader compatibility with standard players and tools.

What applications open OGA files?

VLC, Firefox, Chrome, and Linux media players can handle OGA files. Most are available as free downloads for major operating systems.

How is the OGA audio quality?

OGA provides good quality at standard settings. The output clarity depends on the original PVF recording quality.

How fast is the conversion?

Both formats produce manageable file sizes. The PVF to OGA conversion finishes almost instantly on our infrastructure.

Are my files kept private?

PVF uploads are removed right after processing. All OGA output files are cleaned from servers within 24 hours.

Does this work on mobile?

Yes. The converter runs in any browser — smartphones, tablets, and desktops all work for PVF to OGA conversion.
