sound recording program

Delphi is a inprise (former Borland) company's excellent visual programming tool, its own MediaPlayer control is the development of multimedia tools. It takes a few minutes to make a program like Jie Ba that can play multimedia files. But perhaps few people know that it can also be used to make a recording program. Run Delphi, drag a MediaPlayer control onto the

Dependencies: 1 # pragma comment (Lib, "winmm. lib ") Audio input is divided into three steps. 1. Enable the device ----- waveinopen (enable an audio input device ), 2. Start recording ------ start recording with waveinstart 3. Disable the recording device ------- waveinclose. Call waveinreset to clear the buffer that is waiting for the

with win7, who knows it's slow and heartbroken. Someone recommended the everything software, so I downloaded it and found that searching for things on the computer was basically a second kill. It was cool! You can find this software by google. However, it seems that this tool is not needed to solve the current problem. take the following steps: Step 1: Project-project properties. Here I select Chapter003. Of course, you can right-click the corresponding project in Solution Explorer and select

Recently in window is a platform to do a function to capture audio and video through Obs, and through the RTMP protocol to its encoded compressed data into its own program, since the OBS software with very powerful game recording and desktop recording functions, as well as input, output audio device data acquisition and mixing function , the current fight fish ga

Recording Using the Winsock protocol will slow the response time during playback. This is mainly because the content received by recv_buff during recording is inconsistent with that during playback. The system will automatically check the content. Solution: Add a function in the program: lrs_set_recv_timeout2 (), so that the system does not check whether the rec

Compared with mediarecorder, The audiorecord class is closer to the underlying layer and has fewer encapsulated methods. However, the audio recording program that implements an audiorecord is also very Simple. The sample code is as follows: It is a pity that there is a problem in this instance testing. During recording, there will be buffer over. Cache leakage t
