	lossyWAV is a [[Wikipedia:Free software\|free]], [[lossy]] pre-processor for [[PCM]] audio contained in the [[~~RIFF_WAVE~~\|WAV]] file format. Proposed by [http://www.hydrogenaud.io/forums/index.php?showuser=409 David Robinson], it reduces [[Wikipedia:Audio bit depth\|bit depth]] of the input signal, which, when used in conjunction with certain lossless codecs, reduces the bitrate of the encoded file significantly compared to unpreprocessed compression.		lossyWAV is a [[Wikipedia:Free software\|free]], [[lossy]] pre-processor for [[PCM]] audio contained in the [[RIFF WAVE\|WAV]] file format.

	lossyWAV is based on the lossyFLAC idea proposed by [http://www.hydrogenaud.io/forums/index.php?showuser=409 David Robinson] at Hydrogenaudio, which is a method of carefully reducing the bitdepth of (blocks of) samples which will then allow the FLAC lossless encoder to make use of its wasted bits feature. The aim is to transparently reduce audio bit depth (by making some lower significant bits ([[Wikipedia:~~Least_significant_bit~~\|lsb]]'s) zero), consequently taking advantage of FLAC's detection of consistently-zeroed lower significant bits within each single frame and significantly increasing coding efficiency.[http://www.hydrogenaud.io/forums/index.php?s=&showtopic=55522&view=findpost&p=498179] In this way the user can enjoy audio encoded using the same codec (which may be all important from a hardware compatibility perspective) at a reduced bitrate compared to the lossless version.		lossyWAV is based on the lossyFLAC idea proposed by [http://www.hydrogenaud.io/forums/index.php?showuser=409 David Robinson] at Hydrogenaudio, which is a method of carefully reducing the bitdepth of (blocks of) samples which will then allow the FLAC lossless encoder to make use of its wasted bits feature.

	It must be stressed that lossyWAV is a pure variable bit-depth pre-processor in that the overall sample size remains the same after processing but the number of significant bits used for the samples in a codec-block can change on a block-by-block basis. Bits-to-remove from the audio data are calculated on a block-by-block basis (codec-block length = 512 samples, 11.6msec @ 44.1kHz) using overlapping [[Wikipedia:fast Fourier transform\|fast Fourier Transform]] (FFT) analyses of at least two lengths (default quality preset (-q 5) = 32, 64 & 1024 [[Wikipedia:Sampling ~~%28signal~~ processing~~%29~~\|samples]]). After some manipulation, the results of each FFT analysis for a specific codec-block are then grouped and the minimum value used to determine bits-to-remove for the whole codec-block. Bit removal adds noise to the output, however the level of the added noise associated with the removal of a number of bits has been pre-calculated and the number of bits to remove will depend on the level of the noise floor of the codec-block in question. The added noise is adaptively shaped by default, however the user can select parameters to make the added noise fixed shaped or simply [[Wikipedia:white noise\|white noise]]. Each sample in the codec-block is then rounded such that the first <bits-to-remove> lsb's are zero. In this way the wasted bits feature of [[FLAC]] et al. is exploited.

	lossyWAV is a [[Wikipedia:Free software\|free]], [[lossy]] pre-processor for [[PCM]] audio contained in the [[RIFF_WAVE\|WAV]] file format. Proposed by [http://www.hydrogenaud.io/forums/index.php?showuser=409 David Robinson], it reduces [[Wikipedia:Audio bit depth\|bit depth]] of the input signal, which, when used in conjunction with certain lossless codecs, reduces the bitrate of the encoded file significantly compared to unpreprocessed compression.		lossyWAV is a [[Wikipedia:Free software\|free]], [[lossy]] pre-processor for [[PCM]] audio contained in the [[RIFF_WAVE\|WAV]] file format.
