[TECHNICAL INFORMATION]
ModPlug Player is a 32-bit Windows 95/NT4 application, currently
not using any hardware acceleration, but featuring a lot of options
to create the best possible output (Up to 48KHz, 16-bit, stereo):
- 32-bit internal precision for mixing, dithered to 16-bit.
- Cubic and quadratic spline resampling with MultiPoint resampling selected.
- Automatic click removal.
- Digital Bass Expansion digital low-pass filter (filter range and depth
  customizable in Advanced Player Options)
- Dolby Pro-Logic Surround support (and it's not only negating the right
  channel) with custom delay and 100Hz-7KHz filter depth.
- Reverb Option (not echo), much better since v1.41.01
- Noise Reduction: attenuation of the very high requencies in the sound.
- Stereo Separation option (25%-400%), useful for headphones.
- 40-bands (Or 2x 19-bands) fourier spectrum analyzer, and VU-Meter.

=============================================================================

SETUP:
------

  Clicking on the Setup button will bring a 4 property pages
  dialog:

  - Soundcard Setup / Soundcard Advanced Setup:
  ---------------------------------------------
    * Mixing quality:
      Select the output quality (A CD-ROM is 44.1KHz).
      If you don't want to take too much CPU, 32KHz is a good
      compromise between CPU and audio quality.
      A 32-channels IT module played at 48KHz,stereo can take up
      to 100% of the CPU on a DX2-66 (Especially with Spectrum Analyzer).
      Note: I noticed that 48KHz output can create noise on some
      sound cards, because the hardware is downsampling it to 44.1KHz.
      In this case 44.1KHz is much better (Come on, it's only 4KHz
      difference, you don't need to upgrade your sound card).

    * Stereo:
      This will create a stereo output.
      Playing in mono takes less CPU than in stereo.
      You need to have the stereo option enabled to hear panning
      effects and surround sound.

    * 16-Bit:
      You are strongly advised to use this option, unless your
      soundcard doesn't support stereo playback.
      Playing in 8-bit mode doesn't decrease the CPU usage.

    * Sound buffer length and Number of buffers:
      This option configure the size of the buffer sent to the soundcard.
      (Total length = SoundBufferLength*NumberOfBuffers milliseconds)
      If you are using a small buffer, the player will respond faster
      when you change the player options or move the Pre-Amp slider.
      At the same time, if the PC is very busy in a multitasking
      environment, the sound may get cut from time to time.
      The buffer length must be between 50ms and 250ms.
      The bigger the buffer length, the slower the spectrum analyzer will
      be updated.
      The default settings should work fine, but you may want to increase
      it if you are using CPU-intensive applications, or decrease it if
      you have a very fast PC.

    * Stereo Separation:
      This allows you to control the stereo separation between right and
      left channel. You may want to decrease it with headphones, or increase
      it to feel a stronger stereo. This works only in stereo mode.

    * Maximum Mixing Channels:
      This allows you to control the CPU usage of ModPlug, by limiting the
      number of channels simultaneously playing. It can make a big difference
      in CPU with IT modules using NNA effects. Typically, most modules
      (MOD/S3M and XM) don't go over 16 simultaneous channels, and IT modules
      usually don't go over 32 simultaneous channels. But mixing 32
      simultaneous channels can take 100% of the CPU on a 486DX4-100,
      especially if you're using MultiPoint oversampling, or other DSP
      effects. This option will automatically take care of this problem.

    * Use Function Callback:
      Some drivers (and most Windows NT drivers) don't support the thread
      callback option: in this case, you will hear about half a second of
      sound and it will stop. If this happens, check this box.
      (ModPlug auto-detect NT, and check it under Windows NT)

    * Real-Time Priority:
      This option enables you to control if ModPlug uses a real-time thread
      or a regular high-priority thread. Depending on your sound driver, it
      may improve the response of the player when running in the background.
      Since, v1.25, it also changes the priority of the ModPlug Player process,
      and it should not drop sound anymore with this option enabled.
      I recommend using this option. If you don't have at least a Pentium 133MHz,
      you should use the "Limit CPU usage" combined with this option, or else
      ModPlug could slow down the computer so that it's almost impossible to
      stop the player.

    * Use MMX acceleration:
      This checkbox is grayed if your processor doesn't support the Intel MMX
      instruction set. Note that the player may not take a lot less CPU with
      this option enabled on Pentium II processors, because the multipoint
      resampling will be used more often for slightly better quality, and P2
      have a very fast non-MMX integer multiply. Also, MMX doesn't accelerate
      32-bit operations very well, so the difference in speed may be very small
      for high quality sound mixing.

    * Use DirectSound Secondary buffers:
      This mode is only intended for compatibility problems. If directsound
      doesn't work, you can try to enable this option to see if it's better.
      But if you're using a non-accelerated sound card, directsound is likely
      to output everything at 22KHz using a crappy resampling :(

    Note: If you choose a setting that your soundcard doesn't support,
      the player will ignore it.

  - Player Setup:
  ---------------

    * Spectrum analyzer:
      When this option is checked, ModPlug Player will display the frequency
      spectrum of the sound (using Fourier analyzis). This takes more CPU and
      doesn't affect the quality of the sound. When the player window is behind
      another window or is minimized, the spectrum is not calculated and doesn't
      take any CPU. The frequencies in the spectrum display range from 86Hz
      to 11KHz (There is up to 40-bands). It takes about 15-20% of the CPU on
      a fast Pentium machine, so you shouln't use it with a 486.

    * Stereo Spectrum:
      When this option is checked, together with the Spectrum Analyzer, the
      player will display one spectrum for the left and right channels.
      (In this case, there is 2x19 bands in the spectrum, and the range
      for each channel is from 86Hz to 8KHz). It doesn't take more CPU than
      the mono spectrum analyzer. (You need to play in stereo mode to use this
      option, or else you'll see the same on each channels, duh!)

    * Reverb:
      This will create a reverb effect on the sound, using four delay lines
      with cross feedback and early reflection, and two digital filters.
      You can change the reverb depth (Dry/Wet mix) and preset in the
      Advanced Player Setup. Note that the reverberation engine has been
      completely redesigned in v1.41.01.

    * Pro-Logic Delayed Surround:
      This options sends part of the the sound to the Dolby Pro-Logic
      Surround channel (center + rear speakers) with a delay of about 5
      to 50ms, filtering frequencies from 100Hz to 7KHz. This option works
      only with Stereo enabled. You can change the surround depth and delay
      in the Advanced Player Setup.

    * Noise Reduction:
      Use this option only at 44.1KHz or 48KHz, or else it will filter
      all the high frequencies. It's basically a -3dB lowpass filter running
      at Fs/4 (Fc=11kHz at 44kHz). I really don't recommend using this, but
      it seems some people like it, so that's the only reason why it's still
      here.

    * Bass Expansion:
      This option will make the player doing a 2x bass amplification
      of the sound at 50KHz (About 1.6x at 44.1).
      It takes a little bit more CPU, but not that much.
      If you like low frequencies, or just want to make you neighbour
      upset, that's the option you'll need.
      You can change the XBass depth and delay in the Advanced Player Setup.

    * Disable Resampling:
      I don't recommend using this option, but I had request from people to
      put it back. The player will be much faster, but no resampling is
      performed, so the quality is pretty bad, creating very high frequencies
      in the signal.

    * Enable Multi-Point oversampling:
      You shouldn't use this option if you're working on other applications
      with ModPlug in the background, because it takes much more CPU for a
      small difference in sound quality (But i way be useful when recording
      WAV files).
      By default , the player is using a 256x linear resampling to create
      a smooth sound. At the same time, the linear oversampling decreases
      a little bit the magnitude of the sound, especially on high frequencies.
      With Multi-Point oversampling, it enables two different algorithms for
      resampling, creating a spline using 3 or 4 points.

    * Use Volume Ramping:
      This option doesn't take much more CPU, and instead of jumping from one
      volume to the other, the player will use a volume ramping at the start
      and end of a note, which will remove most of pops and clicks in the sound.
      It will also ramp all volume changes (including volume envelopes), for a
      delay of about 2 milliseconds (very fast), so that no clicks can be created,
      but without slowing down the volume changes.
      NOTE: This is no more an option since v1.36.03: it is always ON.

    * Graphic Equalizer:
      This option is available only on Pentium-Class CPUs, since it uses
      floating-point arithmetic, and I recommend it only for Pentium-II owners.
      I personally always use the 'Clear' preset, since it improves a lot the
      quality of higher frequencies, usually attenuated by the resampler.
      It uses 6 different bandpass filters. Note that you can select the
      senter frequency for each band by right-clicking on the slider.

    * Automatic Gain Control:
      When you open a module with this option enabled, the player will adjust
      the global volume so that there is no clipping, even when the pre-amp
      slider is to the maximum. It can give a better Signal/Noise ratio (SNR).

    * Limit Play Time:
      Enter the maximum playing time of a song (in seconds) before the
      player jumps to the next song. You can also enable/disable the 
      Intro (or Time Limit) mode by the right-click menu.


  - Directories:
  --------------

      * Songs Directory:
        You can enter the path where your mods are located, and the
        player will automatically go to this directory when running.

      * Register Extensions:
        This makes Windows use ModPlug player as the default player
        for all the modules recognized. After clicking this button,
        you can open a song just by double-clicking it in the Windows
        Explorer. If "Use DDE" is selected, each time you open a mod
        it will stay in the same window, or else Windows will open
        another ModPlug Player Window.

      * Clear PlayList When...
        The playlist can be automatically cleared each time you Drag&Drop
        Files in the player window, or when you use the open button.
        (It's always cleared if you open a .MOL file)


  - Plug-ins:
  -----------

      This option allows you to use plug-ins originally made for WinAmp
      (MPEG layer3 Player) with ModPlug Player.
      You have to manually locate one of more plugin libraries.
      The priority option allows you to control the priority of the plugin
      (So it doesn't take too much CPU)
      WARNING:
      * Some plug-ins using DirectDraw won't work while the player is
      using DirectSound, in this case, use a regular Wave Device.
      * Some plug-ins require to be installed in the same directory than
      the player (modplug.exe), so you can either copy modplug.exe in your
      winamp directory, or install a second copy of the plugin in the same
      directory than the player (This is necessary for the Cthugha Plug-in).


  - Packing (now in the Details window):
  --------------------------------------

      The slider allows you to control the quality of packing for the
      Pack As command, and give you information about which samples
      would be packed in the current song. The compression used to pack
      the samples is ADPCM, which can make the file size twice smaller.
      If the compression quality is low, more samples will be packed,
      but you may lose quality. If the compression quality is high, you
      probably won't lose any quality, but less samples will be packed.
      Only use this option if you want to reduce download time for the
      Mod-plugin on a web page, where download time is more important than
      quality (like for a preview of a song).

                 FREQUENTLY ASKED QUESTIONS
     (I'm tired of answering the same emails over and over)
-----------------------------------------------------------------

Q: The channel display is buggy: sometimes it writes 05/04 channels!
A: This is not a bug. The internal click-removal never cuts channels
   but fade them down for 2 milliseconds, so this adds channels to be
   mixed. Also, with IT NNA effects, you can mix a lot more channels.
   The first number is the current average polyphony (on 1 sec). The
   second number is the number of channels in the song.

Q: Sometimes, the Details window displays something like 100 patterns,
   and says than 150 are different!
A: This isn't a bug either (I should amke this text more clear): it means
   that there is 100 patterns (music blocks) played in the song, but 150
   are saved in the file: i.e. 100 of them are not used (hidden patterns?).

Q: How do I uninstall Modplug Player, or the Mod-Plugin ?
A: Find the file "modplug.exe" and drag it to the recycle bin.
   Remove also this file: readme.txt, that should be in the same folder.
   Modplug saves its settings in the registry, under the following key:
   "HKEY_CURRENT_USER\Software\Olivier Lapicque\Modplug Player"
   For the plugin, find the file "NPMOD32.DLL", and send it to the
   recycle bin.

Q: What language did you use to program ModPlug Player ?
A: C++, and a little bit of inline assembly (asm for MMX, EQ and the C parts
   where the compiler really sucked).

Q: I have a non-MMX Cyrix P166, how come the Equalizer is disabled ?
A: Like 486s, most Cyrix processors do not have a good enough floating point
   performance to perform the EQ (Come on! time to get a K6-2 or P2).
   (You should be able to test it by selecting an EQ preset, and then use the
   'E' shortcut, but it will be disabled each time you go back to the setup
   screen - but believe me, you'll quickly turn it back off when you'll see
   your CPU usage jump to 95%)

Q: Do you speak french ?
A: Yes. I am originally from France, but I'm now working in California, in the
   so-called 'Silicon Valley' (Obviously, I also speak english, in case you
   were wondering).

Q: I'm using Windows NT 4.0, and I can't get directsound to work
A: DirectSound isn't supported under NT 4.0. I personally don't recommend using
   DirectSound with the player, since DSound isn't really designed for background
   applications. Use the regular Wave device instead for the player, but
   definitely use DirectSound with Modplug Tracker (because of the lower latency)

Q: When I save a file under a different format, it sounds really different.
A: Don't convert between different file formats using Modplug Player: it is
   much better done using Modplug Tracker. Also: don't convert anything recent
   to a MOD, since you'll lose most of the effects, instrument envelopes, and
   all samples will be converted to 8-bit and truncated to 64KB.

Q: I can't get the player to pan 100% left or 100% right
A: Reverb, Surround and Bass Expansion create feedback from one channel to
   the other.
