*************************************************** * * * Eternal SPU Plugin v.1.41 * * Official Manual * * * *************************************************** What's new? v.1.40 -> v.1.41 (31 May, 2003) ------------------------------------------------------------------------ * Fixed a problem that the record file got broken if SPU was closed during recording. * Fixed a bug in new interface, i.e. SPUplayCDDAchannel(). * Revised the recovery algorithm when the XA buffer over/under-flows. * Fixed some other small bugs. What's new? v.1.30 -> v.1.40 (17 May, 2003) ------------------------------------------------------------------------ * The first release with Eternal SPU plugin Linux port. * Additional audio devices are supported. SDL (Simple DirectMedia Layer) and WaveMapper are added to Windows port, and SDL and OSS are supported by Linux port. * Additional three reverb algorithms are implemented ("Freeverb","Iori's" and "Neill's"). Reverb type "Neill's", which is based on the result of analysis by Neill Corlett, must reproduce the most accurate reverb effect of real PSX. Thanks to Neill Corlett. * Pseudo-Noise emulation codes are completely revised. We believe that the noise sound gets nearly perfect. * Accuracy of pitch modulation is improved. Pitch errors in some games are fixed. We also believe that the pitch modulation gets nearly perfect. * Now, decoded result of XA sound can be read-back from sound buffer using DMA. The level meter of "Tales of Destiny" gets working. * Fixed the sound problem with some Konami's games like "Jikkyo Oshaberi Parodius". * Recovery algorithm in buffer overflow for XA stream is changed to get less noisy sound. * The "Record" function is completely replaced. Although the new SPU file format is incompatible with old one, is able to record register read/write, DMA read/write, XA stream and CDDA stream. * "Cache VAG decode" option added. Faster, but less compatibility. We recommend not to enable this option because some of games will make odd tones. * Mixing algorithm for wet component of reverb is changed. * Obsoleted the gray check of "Update before accessing register" option. * SPUasync - Smooth is fixed. Now it can work even with "Update before accessing register" option. * Information for developer of PSX emulator: We added new interface for CDDA stream to improve compatibility. i.e.: void CALLBACK SPUpalyCDDAchannel( short *pcm, int nbytes); This function enables to play CDDA sound through SPU plugin, and DMA read-back of CDDA waveform from SPU sound buffer will get working.

Introduction ------------------------------------------------------------------------ Eternal SPU Plugin is a sound plugin for PlayStation emulators. You can use this plugin on following PlayStation emulators. - PSEmu Pro : discontinued - ePSXe : http://www.epsxe.com/ - AdriPSX ILE : http://www.adripsx.com/ - PCSX : http://www.pcsx.net - PSinex : http://psinex.psxemu.com/ - FPSE : discontinued ------------------------------------------------------------------------ 1. Usage ------------------------------------------------------------------------ First, copy "spuEternal.dll" (for Windows) or "libspuEternal.so.1.41" (for Linux) into the plugin folder of emulator. After running the emulator, select [Eternal SPU Plugin x.x] in sound plugin configuration dialog. In case of ePSXe, you can call it by hitting [Config] button. If you finished config, reboot emulator. Enjoy! ------------------------------------------------------------------------ 2. Configuration ------------------------------------------------------------------------ 2-1-0. [Audio device] - DirectSound / SDL / WaveMapper / OSS You can select the audio device. [DirectSound] : Output sound using DirectSound. Need DirectX3 or higher. Windows version Only. [SDL] : Output sound using SDL (Simple DirectMedia Layer) Library. For Windows version, you must install "SDL.dll" into one of the following directories. 1. The directory in which the emulator is installed. 2. The system directory. 3. The directories listed in the PATH. Similarly, it is required that "libSDL.so" is properly installed for Linux version. [Wave Mapper] : Output sound using standard Windows Wave Mapper. It can't be used in a system which has no Wave devices. Windows version Only. [OSS] : Output sound using OSS (Open Sound System(TM)) driver. Linux version Only. ------------------------------------------------------------------------ 2-1-1. [Audio device] - Buffer size You can set the Sound buffer length between 0 and 999. Although default value is [64], you should set value by your own. * Smaller value will give shorter sound delay. * If the value is too small, the sound will be noisy. ------------------------------------------------------------------------ 2-2-0. [Audio out method] - Thread / Timer / SPUasync You can select the audio output method. Please set the method which best fits your PC. [Thread] --> Compatibility is higher than [Timer]. Load is higher than [Timer]. [Timer] --> Compatibility is lower than [Thread] Load is lower than [Thread]. [SPUasync] --> Compatibility is the highest. * When you use this function, it may be necessary to set [buffer size] larger than the others, or sound will be very noisy. * Must be supported by emulator. ------------------------------------------------------------------------ 2-2-1. [Audio out method] - Async mode You can select the mode of SPUasync. [Simple] --> This mode doesn't perform complicated processing. If frame rate is high or low, a sound will be choppy. SPU is always synchronized with PSX CPU core. [Wait] --> When frame rate is high, gives the waiting to become the optimal frame rate. When the frame rate is low, clears a delayed part to prevent repeating the same sound. SPU is always synchronized with PSX CPU core. [Smooth] --> SPU trims it's processing speed dynamically followed to frame rate. As a result, SPU may act asynchronously with PSX CPU core. Although sound won't be choppy with higher or lower frame rate, following games which use SPU-IRQ may cause some problems with this setting as well as "Thread" or "Timer". Ex.) * Valkyrie Profile <ENIX> * Star Ocean 2 <ENIX> * MetalGear Solid <KONAMI> ...etc ------------------------------------------------------------------------ 2-3-0. [Misc] - Show realtime config window Show configuration window during emulation to change settings. You can use this option in case of window mode only. ------------------------------------------------------------------------ 2-3-1. [Misc] - Wait for XA buffer is free This function has emulator to wait for XA buffer is free to be able to put all XA data into XA buffer. * During reproduction of XA, even if you removes FPS limit, you can't change the speed of emulator. * Emulator's motion may become unstable. ------------------------------------------------------------------------ 2-3-2. [Misc] - Cache VAG decode In order to make processing fast, cash the decoded sample for every VAG block. This function still has some problems. ------------------------------------------------------------------------ 2-3-3. [Misc] - Fine tune You can set the pitch of sound. 10 : 1 half pitch high -10 : 1 half pitch low 120 : 1 octave high -120 : 1 octave low ------------------------------------------------------------------------ 2-3-4. [Misc] - Reverb You can select the Reverb emulation type. [Off] --> No reverb effect. [TiMidity] --> Reverb used by TiMidity. The same reverb effect with previous version. [Freeverb] --> Reverb used by Freeverb. One of the nice alternatives. [Iori's] --> Reverb developed by Iori in try and error. Another alternative. Less accurate than "Neill's", but high quality effect. [Neill's] --> Reverb based on the result of analysis by Neill Corlett. Most accurate one. ------------------------------------------------------------------------ 2-4-0. [Special game fix] - Update before accessing register These are options for...
