	'''OptimFROG''' is a [[lossless]] audio [[codec]] with optional [[Hybrid codec\|hybrid lossless/lossy]] encoding. It comes with a freeware (closed-source) command-line encoder/decoder and plugins for several players and processing front-ends, and an SDK to use in other applications. It is available for Windows, Linux, FreeBSD and MacOSX, all in both 32-bit and 64-bit versions.

These presets are CPU intensive both for decoding and encoding, sometimes a 10x increase over the faster presets, where OptimFrog would compress about the speed of [[Monkey's Audio]] “Extra High” and achieve compression ratios like Monkey's “High”.

The current OptimFrog version has introduced new presets aiming at improving the speed/compression trade-off.)

	~~One of its downsides is that there is no source code available, nor format specifications. Another downside is that it is relatively slow at both encoding and decoding.~~

	OptimFROG uses a new audio compression technology, the generalized stereo decorrelation concept, which was first introduced with OptimFROG 4.0b in December 2001. At the time of its introduction, the new technology yielded significant better (~1.5%) compression than existing state of the art lossless audio compressors.

	==Software support==
			== Features ==
			For an end-user considering OptimFROG as a an audio format - likely due to its compression ratios or possibly its hybrid mode - some of the following features are quite common among lossless codecs, while some are more scarce - in particular, the end of this list. To compare OFR with other lossless codecs, see [[Lossless_comparison\| HA Wiki's Lossless Codec Comparison]].

			* Streaming support
			* Seekable playback
			* Error handling. Audio checksum for integrity verification optional (use the --md5 option)
			* High-resolution audio support up to 32 bits per channel. Like [[WavPack]] but unlike most other formats, it also supports floating-point format (through a different executable included in the distribution). OptimFrog works with higher sampling rates, but the maximum supported sampling rate seems undocumented.
			* Piping support for encoding, and support for RAW PCM input.
			* Tagging: ID3 or APEv2 tags.
			* RIFF chunks supported for recreating also non-audio chunks of the original .wav files.
			* Can read certain malformed .wav files; in particular, some hacks employed to fit more than the 4 GB size limitation into .wav files.
			* Like WavPack, but unlike most other encoders, it can create Windows self-extracting .sfx archives.
			* Hybrid lossy/lossless encoding supported. Like WavPack, but unlike most (every?) other end-user codecs, OptimFROG can decode both lossy and lossless streams together, to be maintained in the same library. A separate encoder is included in the distribution.


			=== Limitations ===
			* Currently there is no hardware supporting the format and software support is limited. The official encoder/decoder is closed-source (but a an official library can be used in third-party applications). Also the format has no official specification.
			* Encoding and also decoding is CPU intensive, especially in the higher modes. Given that portable low-power devices are out of consideration as they cannot play the files anyway, speed might not be that much of a limitation with the power of modern computers. Still, users who consider playing OptimFrog files from a battery-powered laptop or tablet, might want to test battery life impact, especially since it varies so much over the settings.
			* No multichannel support.

			Because OptimFrog - like MP3 - can accommodate both APE tags and ID3, tagging ambiguity could be an issue: one application might not read another's tags. A user would likely want to stick to one tag format. Mp3tag will by default write APE tags to .ofr files.
