On playback, listeners may decide if they want all tracks to sound equally loud or if they want all albums to sound equally loud with different tracks having different loudness.
Using the album-gain values during playback will preserve the volume differences among tracks on an album. In album-gain analysis an additional peak-value and gain-value, which will be shared by the whole album, is calculated. Analysis can also be performed on a per-album basis. ReplayGain analysis can be performed on individual tracks, so that all tracks will be of equal volume on playback. The more recent EBU R 128 suggests 23 dB. In contrast, the SMPTE RP 200:2002, on which the ReplayGain reference was originally based, recommends 20 dB of headroom. ReplayGain nominally plays at -14 dB relative to full-scale leaving 14 dB of headroom for reproduction of dynamic material. Ī more common means of specifying a reference level is relative to a full-scale signal.

The SPL reference comes from a SMPTE recommendation used to calibrate playback levels in movie theaters. The target loudness of ReplayGain utilities is 89 dB sound pressure level. Some lossy audio formats, such as MP3, are structured in a way that they encode the volume of each compressed frame in a stream, and tools such as MP3Gain take advantage of this for directly applying the gain adjustment to MP3 files, adding undo information so that the process is reversible. Alternatively, a tool can amplify or attenuate the data itself and save the result to another, gain-adjusted audio file this is not perfectly reversible in most cases. ReplayGain utilities usually add metadata to the audio files without altering the original audio data. Updating macOS may break other legacy applications on your Mac. Other formats such as AAC and WMA use their native tag formats with a specially formatted tag entry listing the track's replay gain and peak loudness. FLAC and Ogg Vorbis use the REPLAYGAIN_*Vorbis comment fields. Most implementations now use tags for ReplayGain information. The original ReplayGain proposal specified an 8-byte field in the header of any file. The peak level metadata can be used to prevent gain adjustments from inducing clipping in the playback device. ReplayGain-capable audio players use the replay gain metadata to automatically attenuate or amplify the signal on a per-track or per-album basis such that tracks or albums play at a similar loudness level. Typically, the replay gain and peak level values are then stored as metadata in the audio file. The difference between the measured perceived loudness and the desired target loudness is calculated this is considered the ideal replay gain value. Equal-loudness contours are used for to compensate for frequency effects and statistical analysis is used to accommodate for effects related to time. ReplayGain works by first performing a psychoacoustic analysis of an entire audio track or album to measure peak level and perceived loudness. Decibel Player For Macbook Air Operation

ReplayGain is supported in a large number of media software and portable devices. Decibel is an audio player tailored to the particular needs of audiophiles.Īlthough this de facto standard is now formally known as ReplayGain, it was originally known as Replay Gain and is sometimes abbreviated RG. With the release of OS X Apple discontinued ASIO support. The ASIO protocol developed by Steinberg used to be the preferred sound technology on Mac computers.

Decibel - a very straightforward to use Mac OS X audio player with a clean and user friendly interface - becomes the first Mac OS X audiophile-grade player with ASIO support. Vox supports common files like FLAC, MP3, CUE, and APE, as well as high-resolution audio files for up to 5.1 channel support - ideal if you have your Mac connected to a larger speaker system. This avoids the common problem of having to manually adjust volume levels between tracks when playing audio files from albums that have been mastered at different loudness levels. It allows media players to normalize loudness for individual tracks or albums. ReplayGain is a proposed standard published by David Robinson in 2001 to measure and normalize the perceived loudness of audio in computer audio formats such as MP3 and Ogg Vorbis.
