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

[Linpiu] from the true audio homepage, the compression ratio is not very high. I think this is why it is not as popular as FLAC and ape. Record the information and study it later.Algorithm.

In a big aspect, the android audio system architecture has not changed much compared with Android. The analysis of the audio architecture of 2.2 still applies to 2.3. Many people have already elaborated on this aspect in detail and I will not repeat it here. The storage location of files in each module has changed, so you need to understand this. 1. A major improvement is the introduction of the mixable

The so-called multimedia computers usually have sound cards (soft or hard sound cards), which can capture audio. You must be familiar with the attachment "recorder" program that comes with windows. You can use a microphone for recording and generate a wave file. After reading this article, you will find that using DirectShow to write an audio capture application is also so easy! As you know, DirectShow sup
