[Multimedia Develop] MIDIWrapper_Src DL : 0: Using the Windows low-level MIDI API is not necessarily easy. There are a lot of details to keep track of, and it can get a bit frustrating when you are trying to write a MIDI application. The goal of my small wrapper library is to elevate some of the grunt work that goes into using the Windows low-level MIDI API by encapsulating the functions into C++ classes. With these classes, most of the dirty work is handled behind the scenes. This leaves you free to concentrate on more important matters.-Using the Windows low-level MIDI API is not necessarily easy.

[Multimedia Develop] MFFMBitStream DL : 0: MFFM Bit Stream A C++ heirachy for reading and writing bit streams. Implemented for maximum efficiency/ease of use. Write or read bit streams for audio and video protocols such as mpeg (mp3), H.263, etc. Many parallel streams could be used in logic syntax streams as well Operating System: OS Independent (Written in an interpreted language)-MFFM A Bit Stream C heirachy for reading and writing bit streams.

[Multimedia Develop] 54668-54668 DL : 0: This code provides information about the Windows Bitmap file format along with source code for some classes that can load and save bitmaps. Loading supports all bit depths(1,4,8,16,24,32) but not compression(rarely used anyway). Saving supports bit depths 16,24,32. If you prefer c++, check my submissions for a c++ version. -This code provides information about the Windows Bitmap file format along with source code for some classes that can load and save bitmaps.

[Multimedia Develop] gsm-1.0.13.tar DL : 1: The low level speech compression algorithm of the GSM suite is called GSM 06.10 RPE LTP (Regular Pulse Excitation Long Term Predictor). My colleague Dr. Carsten Bormann and I have implemented a GSM 06.10 RPE LTP coder and decoder in C. Its source code is freely available, and we encourage you to use it, play with it, and invent new real time media protocols and algorithms. Our implementation consists of a C library and a stand alone program. Both are destined to be compiled and used on a Unix like environment with at least 32 bit integers, but others have ported it to VMS and a MS DOS 16 bit environment. GSM 06.10 is faster than code book lookup algorithms such as CELP, but by no means cheap to use it for real time communication, you will need at least a medium scale workstation. -The low level speech compression algorithm of the GSM suite is called GSM 06.10 RPE LTP (Regular Pulse Excitation Long Term Predictor).

[Multimedia Develop] hw_wave DL : 0: Mini project - 2: 使用弦波合成音乐 1. 将主旋律请使用以下的简谱为主，C大调 http://www.jitay.com/pic/201406/948.html 2. temple = 120 (也就是0.5秒为一拍) 3. 音档格式: *.wav档，sample rate: 44.1kHz, bit depth=16bits, channel: 2 (stereo)，所以要有wav档的header，让window media player可以直接拨出。 4. 弦波的振幅: 15-Mini project- 2: 1. Use the main theme music synthesis sine wave Please use the following notation based, C major http://www.jitay.com/pic/201406/948.html 2. temple = 120 (that is, 0.5 seconds for a film) 3. audio file formats:* .wav files, sample rate: 44.1kHz, bit depth = 16bits, channel: 2 (stereo), so there must be a wav file header, so that you can directly dial window media player out. 4. The sine wave amplitude: 15000
