What is the bit rate of the Minidisc's ATRAC audio after compression?
Minidisc Frequently Asked QuestionsFor a stereo signal it's 292162.5 bits/sec. ATRAC compresses 512 incoming 16 bit samples (1024 bytes) into one ATRAC ''sound group'' (212 bytes) giving an audio compression ratio of 4.83:1. Here is the math: 44100 samples/sec (incoming single channel rate) bits/sec. ATRAC3 (used in MDLP) runs at 132kbps (LP2) and 66kbps (LP4). See the MDLP FAQ for further details. ATRAC is 292kbit/sec, giving ''CD like'' audio fidelity. MPEG Layer 1 (i.e.

Related QuestionsWhat is the rate of audio compression used with VoIP?
Frequently Asked Questions-BitWare TechnologiesThere are several methods for audio compression used with VoIP. Some of the most commonly used are G.729, G.711, G.723.1. G.729 is the most prevalent standard of voice compression used with VoIP and typically compresses a 64 kbit/s voice signal to 8 kbit/s in 10 millisecond chunks, however, extensions exist to compress data to 6.4 kbit/s and 11.8 kbit/s with marginally better or worse voice quality respectively. In situations where G.
Related QuestionsCan an MD Data drive be used to access the ATRAC data on an MD Audio disc?
Minidisc Frequently Asked QuestionsNo, there is a read-only label track on each MD that distinguishes an MD Audio and MD Data disc, MD equipment looks at this label to determine what kind of disc it is accessing. An MD audio disc inserted in an MD Data drive shows up as having 1k in disc, 0k available. The ATRAC encoded music information is not accessible. An MD Data drive user has written some information about the MD Data drive and cross compatibility.

Related QuestionsWhat is ATRAC?
Saul Mineroff Electronics, Inc. Mini Disc Recorder FAQ (Freq...ATRAC stands for Adaptive Transform Acoustic Coding. Atrac is a very intelligent compression method; it doesn't just blindly toss out data. ATRAC attempts to follow the perceptual model of human hearing to determine what the human ear can and cannot hear. Anything determined to be inaudible or masked by other sounds is where the compression occurs. The end result: Audio that sounds (to the human ear) exactly like the original, but at 1/5 the original size.

Related QuestionsIs Variable Bit Rate allowed in MPEG-1 and MPEG-2 Audio?
MPEG Audio FAQ Version 9For Layer III, the answer is simply 'yes'. For Layers I and II, according to the standard, it is not mandatory for decoders to support Variable Bit Rate (VBR). However, in practice the majority of the decoders do support Variable Bit Rate, and it is perfectly in line with the standard to specify for a certain application that decoders should support VBR.

Related QuestionsWorldly Voices Technical FAQBit rate (or bit depth) describes how many binary digits a digital audio file uses to describe the amplitude of the audio it is recreating. Each bit doubles the accuracy with which an amplitude level can be described (16 bit = 65,536 possible levels). This means that bit rate can also be said to determine the signal to noise ratio (or dynamic range) of an audio file (16 bit = 96dB of theoretical usable space in which to represent your audio).Related Questions

Related QuestionsIs the same video compression applied to audio ?
MPEG-1 VideoDefinitely no. The eye and the ear, even if they are only a few centimeters apart, works very differently. The ear has a much higher dynamic range and resolution. It can pick out more details but it is slower than the eye. The MPEG committee chose to recommend 3 compression methods and named them Audio Level I, II and III. Level I is the simplest, a sub-band coder with a psycoacustic model (You'll get the details of this stuff further on).
Related QuestionsHow good is MPEG-1 AUDIO compression ?
MPEG-1 VideoMPEG can compress to a bitstream of 32kbit/s to 384kbit/s (Layer II). A raw PCM audio bitstream is about 705kbit/s so this gives a max. compression ratio of about 22. Normal compression ratio is more like 1:6 or 1:7. If you think that this is not much please remember that unlike video we are talking about no perceivable quality loss here. 96kbit/s is considered transparent for most practical purposes.

Related QuestionsWhat actual changes have been made to ATRAC over the years?
Minidisc Frequently Asked QuestionsThere is not much information about this other than what Sony says in their brochures and what appears in occasional magazine articles (thanks primarily to Japanese MJ and German Stereo magazines for their detailed reporting). Since ATRAC's transform window size (11.6ms) and signal processing structure are fixed, the improvements come primarily through improvements to the signal processing step's mathematical accuracy and refinements to the bit allocation process.

Related QuestionsWhat is bit-rate and how do I select this?
FAQ about Getdigital's conversion and convert cd to mp3 ripp...Each compression format offers different bit-rates, which are the settings for quality: the higher the bit-rate, the higher the quality of the compressed file. For MP3, common bit-rates are 128kbps (kilo-bits per second), 192kbps, 256kbps, and 320kbps. A 128kbps MP3 file is considered to be "CD quality", with each higher bit-rate resulting in a more exact copy of the original CD. Yes, quality and storage size directly affect each other.
