Media compression

Lossless audio codec

OptimFROG is a codec that gives priority to compression size, sacrificing speed. Its highest presets are compressed to smaller file sizes than any other end-user codec, perhaps except for (legacy/unsupported) La. These presets are resource-intensive for decoding and encoding, sometimes ten times more than faster presets, where OptimFrog compresses Monkey's Audio "Extra High" speed and achieves compression ratios such as Monkey's "High." Positioning itself perhaps at one of the extreme compromises between size and CPU load, it has a relatively small user base - and unlike the most notable codecs, there appears to be no third-party decoder and no sign of reverse engineering the FFmpeg format.

Key features

  • Error handling. The decoder may continue to decode due to errors. The audio checksum is optional (use option --md5 when encoding, --check to check this), but OFR can also check for corruption without decoding (--verify) faster than any decoding format.

  • High-resolution audio support: any sample rate supported by the WAVE format (4 GHz), up to 32 bits per channel. Like WavPack, but unlike most other forms, it also supports a floating-point format (via another executable included in the distribution).

  • Support for encoding pipelines and support for RAW PCM input. Marking. (APEv2 or ID3 - see below.) RIFF chunks are supported to reconstruct non-audio pieces of source wave files; by default, OptimFROG will rebuild a .wav file that is bit-for-bit identical to the original.

Why download OptimFROG Lossless Audio Compressor for Windows?

OptimFROG is a lossless audio codec with additional hybrid lossless/lossless encoding. It comes with a free (closed source) command line encoder/decoder, plugins for multiple players and interface processing, and an SDK for use in other applications. Encoders for hybrid "DualStream" format and for floating point audio are included in the distributions in separate executable files. OptimFROG is a lossless audio compression program. It is similar to ZIP compression but highly specialized to compress audio data. Its main goal is to reduce, at maximum, the size of audio files while permitting bit identical restoration for all input.
