quicktime audio recording

. Perform analysis: Recording: the mic is sent to codec and converted to a digital signal through the ADC. It is stored in the first-in-first-out (FIFO) of the CPU through the ac97 interface in pending 2, and transferred to the memory through the DMA Interface in pending 1, the snd_pcm_readi interface in alsa_lib to be continued 3 is passed to the recording software and encoded to form an

Before I developed my iphone, I knew very little about the sound format. I know some of the differences between "wav" and "MP3" sound formats, but I certainly can't tell you exactly what the "AAC", "CAF" sound file is, and how the best way to convert audio files on your Mac is not known.I know that if you want to be a qualified iphone developer, you have to have a basic understanding of sound file data format, conversion,

Create empty applicaton and add the homeviewcontroller file. Let's look at the code. The theory is too boring and will be mentioned in the code. Homeviewcontroller.

I. Principles In Linux, recording-reads data from the dsp device and playing-writes data to the dsp device. The Development Board uses the sound card UDA1341 to implement audio codec and complete A/D and D/A conversion. The figure below shows the connection between the chip UDA1341 and the CPU: To achieve full duplex, two DMA channels are required for data transmission. Taking

to prepare are set parameters. You can also set other parameters to view the differences. Prepare means that the recording device starts to prepare to capture the data of the input device and encode the data. This means that everything is ready, just wait for the first moment. For the specific code of prepare, see: /** * Prepares the recorder to begin capturing and encoding data. This method * must be called after setting up the desired
