Recording I generally prefer the MCI approach and of course there is another way and DirectSound but it's going to be a lot of trouble.But it has a feature that makes me feel better, first you can choose the source of recording equipment, second it is not like MCIMust write to the local disk, it is to put the recorded audio stream in memory, at the speed I think it will quicklyMuch, but it also has a drawback that makes me uncomfortable, it's not as e
MCI, a high-level interface for controlling multimedia devices under Windows, defines functions and data types that call MCI functionality in The application controls the MCI device by sending a command message to the MCI device.The following code implements the ability to play MP3 playback with
There are three main ways of playing music in C #: 1, system.media.soundplay;2, MCI interface, 3, MediaPlayer control. Soundplay is specifically used to play sound, that is,. wav files, the use of the method is relatively simple. The MediaPlayer control is the system's own player, and it's been introduced a lot.
Today I would like to introduce you to the MCI interface, about the
Recently I have studied playing music in MFC, mainly using MCI.

A few days ago, you need to play a midi music Loop in a Delphi applet. Why not MP3 or WAV or other? Because the MIDI format is small in size. (In short I have my inevitable reason, more spray nonsense meaning)The playback feature is selected using the mciSendString function in MMSystem, and notice that the "OPEN" operation requires the media type "type SEQUENCER" (that is, MIDI audio), and then use the "Play XX REPEAT"Operation want to be able to loop playback, the results not only did not real
MCI is an interface for Windows to provide multimedia devices.
To program MCI, send the mci_open command to open the device ---> send the mci_play command to play the device ----> send the mci_cloase
The mcisendcommand function can be used to send a command to a specified device. The definition of mcisendcommand is as follows:
Mcierror mcisendcommand (
