  12. 1.2.2 Sound generation section
    13. 

  13. ------------------------------
    14. 

  14. 

  15. The Sound generation section is responsible for generating the OPL's
    16. 

  16. sound, according to the input of the Playback section. This sound is
    17. 

  17. either routed back to the application for it to do something with it or
    18. 

  18. routed directly to a specific audio hardware.
    19. 

  19. 

  20.    The following headers provide the interface to the sound generation
    21. 

  21. section: `emuopl.h', `temuopl.h', `kemuopl.h', `realopl.h',
    22. 

  22. `silentopl.h', `analopl.h' and `diskopl.h'. All classes inside these
    23. 

  23. headers are derived from the abstract base class `Copl', declared
    24. 

  24. inside the file `opl.h', which provides the common interface for the
    25. 

  25. Backend layer of the Playback section. This interface is not meant for
    26. 

  26. the Frontend layer (i.e. your application). Your application, however,
    27. 

  27. has to call special methods of these classes in order to route the data
    28. 

  28. back, if there is any.
    29. 

  29. 

  30.    `emuopl.h' provides the class `CEmuopl', which implements a virtual
    31. 

  31. OPL emulator, which automatically selects the best available OPL chip
    32. 

  32. emulation and type for each replayer.
    33. 

  33. 

  34.    `temuopl.h' provides the class `CTEmuopl', which is a wrapper class
    35. 

  35. around Tatsuyuki Satoh's fmopl OPL2 emulator, which generates wave
    36. 

  36. audio data to be routed back to the application.
    37. 

  37. 

  38.    `kemuopl.h' provides the class `CKemuopl', which is a wrapper class
    39. 

  39. around Ken Silverman's adlibemu OPL2 emulator, which generates wave
    40. 

  40. audio data to be routed back to the application.
    41. 

  41. 

  42.    `realopl.h' provides the class `CRealopl', which outputs to a real
    43. 

  43. hardware OPL2 or OPL3 chip. No data is routed back to the application.
    44. 

  44. This class is currently only working on x86 hardware.
    45. 

  45. 

  46.    `silentopl.h' provides the class `CSilentopl', which is a dummy
    47. 

  47. OPL2/3, which generates nothing. All data sent to it is forgotten
    48. 

  48. immediately. No data is routed back to the application.
    49. 

  49. 

  50.    `analopl.h' provides the class `CAnalopl', which is the same as `CRealopl',
    51. 

  51. but also provides a 9-channel loudness pseudo-analyzer interface for
    52. 

  52. the application. The loudness data is the only data routed back to the
    53. 

  53. application.
    54. 

  54. 

  55.    `diskopl.h' provides the class `CDiskopl', which is an OPL3 emulator
    56. 

  56. that does not output any sound to the soundcard, but instead writes all
    57. 

  57. received OPL commands to a file in the RdosPlay RAW format.
