Any comments on this quote from the SimAudio site referenced previously: "32-bit Processing
The digital-to-analog conversion process uses bits of digital information to produce an analog waveform, represented as a sine wave (in this example only a part of a sine wave is shown) to produce a music signal. When more digital information is made available, the result is a more accurate and detailed music signal. *A higher bit-depth (or a higher resolution) yields smaller, finer and more accurate steps in the reconstruction of this sine wave (grey) as seen in the animated figure below. A 32-bit (blue) data stream contains significantly more information than a 24-bit (green) or 16-bit (red) data stream.* As a general rule, increased processing power is directly proportional to resolution: For each additional bit of resolution,the number of availble levels will double, as shown in the following table: Bit Depth/Steps 16 / 65,536 20 / 1,048,576 24 /16,777,216 32 /4,294,967,206 To summarize, the higher the resolution of the data, the smaller the steps will be. This results in more detail as each individual step covers a smaller section of the waveform. More detail in the digital domain leads to a much more analog signal signal at the end of the conversion process. Another major benefit of this 32-bit process is smaller data truncation errors. These errors result from the extensive mathematical calculations performed during upsampling & sampling rate conversion, prior to the D-to-A process. These truncation errors - shown in the above figure, occur when the data sample rises outside (or above) the grey curve - will be signifcantly smaller as bit-depth increases due to finer and more accurate calculations. As well, because of the sheer processing power that's readily available at 32-bits, the errors will not impede the circuit's ability to accurately recreate the music waveform." -- Kellen ------------------------------------------------------------------------ Kellen's Profile: http://forums.slimdevices.com/member.php?userid=16569 View this thread: http://forums.slimdevices.com/showthread.php?t=74102 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/audiophiles
