-/* Linear half-attenuation to log conversion table in the format:
- *   {linear volume, logarithmic attenuation equivalent}, ...
- *
- * Provides conversion from a linear half-volume value in the range
- * [0,8192] to a logarithmic attenuation value in the range 0 to 6.02dB.
- * Halving the linear volume is equivalent to an additional 6dB of 
- * logarithmic attenuation. The algorithm used in log_from_linear()
- * therefore uses this table as follows:
- * 
- * - loop and for every time the volume is less than half the maximum 
- *   volume (16384), add another 6dB and halve the maximum value used
- *   for this comparison.
- * - when the volume is greater than half the maximum volume, take
- *   the difference of the volume to half volume (in the range [0,8192])
- *   and look up the log_table[] to find the nearest entry.
- * - take the logarithic component of this entry and add it to the 
- *   resulting attenuation.
- *
- * Thus this routine provides a linear->log conversion for a range of
- * [0,16384] using only 386 table entries
- *
- * Note: although this table stores log attenuation in 8.8 format, values
- * were only calculated for 6 bits fractional precision, since that is
- * the most precision offered by the trident hardware.
