-mpeg Layer II audio decoder, integer version
-variable type control
-
------------------------------------------------------------------*/
-/*-----------------------------------------------------------------
-Variable types can have a large impact on performance. If the
-native type int is 32 bit or better, setting all variables to the
-native int is probably the best bet. Machines with fast floating
-point handware will probably run faster with the floating point
-version of this decoder.
-
-On 16 bit machines, use the native 16 bit int where possible
-with special consideration given to the multiplies used in
-the dct and window (see below).
-
-
-The code uses the type INT32 when 32 or more bits are required.
-Use the native int if possible.
-Signed types are required for all but DCTCOEF which may be unsigned.
-
-THe major parts of the decoder are: bit stream unpack (iup.c),
-dct (cidct.c), and window (iwinq.c). The compute time relationship
-is usually unpack < dct < window.
-
--------------------------------------------------------------------*/
-
-/*-------------- dct cidct.c -------------------------------------------
-dct input is type SAMPLEINT, output is WININT
-
-DCTCOEF: dct coefs, 16 or more bits required
-DCTBITS: fractional bits in dct coefs. Coefs are unsigned in
- the range 0.50 to 10.2. DCTBITS=10 is a compromise
- between precision and the possibility of overflowing
- intermediate results.
-
-
-DCTSATURATE: If set, saturates dct output to 16 bit.
- Dct output may overflow if WININT is 16 bit, overflow
- is rare, but very noisy. Define to 1 for 16 bit WININT.
- Define to 0 otherwise.
-
-The multiply used in the dct (routine forward_bf in cidct.c) requires
-the multiplication of a 32 bit variable by a 16 bit unsigned coef
-to produce a signed 32 bit result. On 16 bit machines this could be
-faster than a full 32x32 multiply.
-
-------------------------------------------------------------------*/
-/*-------------- WINDOW iwinq.c ---------------------------------------
-window input is type WININT, output is short (16 bit pcm audio)
-
-window coefs WINBITS fractional bits,
- coefs are signed range in -1.15 to 0.96.
- WINBITS=14 is maximum for 16 bit signed representation.
- Some CPU's will multiply faster with fewer bits.
- WINBITS less that 8 may cause noticeable quality loss.
-
-WINMULT defines the multiply used in the window (iwinq.c)
-WINMULT must produce a 32 bit (or better) result, although both
-multipliers may be 16 bit. A 16x16-->32 multiply may offer
-a performance advantage if the compiler can be coerced into
-doing the right thing.
