Channel D, a developer of audio software solutions for Apple Macintosh computers, which includes its Pure Vinyl transcription, archiving and record editing software, recently introduced a new high-resolution digital audio playback software program for Apple iTunes.
According to the company, Pure Music is based on its Pure Vinyl audio playback engine and it automatically docks with Apple’s free iTunes digital jukebox software to handle music playback with a high-resolution playback engine. Channel D says that when iTunes and Pure Music are run together, iTunes will act as the database and playlist organizer, while its software leverages the user’s familiarity of iTunes functions such as track selection, music library navigation, and more. Channel D adds that when these programs are combined with a high-resolution sound card or DAC, Pure Music will deliver a dynamic and detailed audio playback.
Robert Robinson, director of engineering for Channel D, notes that one of the major advantages of the new software release is that it will playback audio files at their natural resolution without downgrading the bitrate and sampling frequency of those files.
“Pure Music offers many benefits over iTunes alone. Foremost, iTunes plays all audio tracks at the sample rate detected when launched. If this were 44.1kHz [CD quality], then all high resolution audio tracks [up to 192kHz/24-bit, which can be purchased and downloaded on the Internet] would be downsampled and played in a CD format, diminishing playback quality. On the other hand, Pure Music will automatically play high-resolution audio tracks at their native sample rate [if supported by the connected sound card or DAC]. This capability was previously only available in costly ($995) audio playback software, but now is available with Pure Music for just $129.”
Channel D continues by stating Pure Music offers more than native file type resolution playback by also offering features such as Memory Play, real-time high resolution upsampling of CD tracks, a 64-bit internal signal path, dithered volume control, subwoofer crossover, multichannel support, audio processing plug-ins, CoreAudio Hog Mode playback, high resolution audio streaming, precision signal metering, reverse play, and it works with all iTunes-supported audio formats, including but not limited to Apple Lossless, AIFF, Wave, AAC and MP3.
