Mac/iphone Multimedia (Pictures, audio and video) handles how to export photos and recorded videos from the IPhone app image captureImage capture transfers images between a digital camera or a scanner and your Mac computer. When a compatible device with a webcam is connected to your computer, you can use image capture to take a photo. You can then use these images in IPhoto or Automator, or share them over the network.Open the Image Capture app and se

The example of this article introduces the method of using winmm.h to obtain the audio stream, the following steps are as follows: First, you need to include the following reference objects #include Second, the acquisition of audio needs to call 7 functions 1. Waveingetnumdevs: Returns the number of waveform sound input devices that are ready in the system UINT Waveingetnumdevs (VOID

On the audio voice changer algorithm, this is a topic that many people are particularly interested in. Of course, there are many open-source algorithms to learn, there are time-domain-based, but also based on the frequency-domain algorithm. The final algorithm wants to achieve the same purpose. Recently there are many netizens asked about the voice changer algorithm some of the details of the problem, e-mail asked me. To give a more reasonable or

The IPhone OS mainly offers several ways to play audio: System Sound Services Avaudioplayer class Audio Queue Services OpenAL 1.

FrequencyDifferent frequency sine wave, the lower part than the upper part frequency high frequency is the unit time the repetition occurrence number measure, in the physics usually by the symbol Roman letter F or the Greek word ν, its international unit is Hertz (Hz). When an event is repeated n times in a T time, this event occurs at a frequency of f = n/t Hz. And because the cycle is defined as the minimum interval of recurrence, the frequency can also be expressed as the reciprocal of the cy

It took me three weeks to solve this problem. When the player of the current product solves the real file with a high resolution and a high bit rate, half of the audio playback will be disconnected, and a small buffer data will be lost, and then continue. The breaking frequency is proportional to the bit rate. Since there is a problem with the audio, of course we should first start to check the
