1.2.1 Common formatsCommon audio formats are: CD format, WAVE (*. WAV), AIFF, AU, MP3, MIDI, WMA, RealAudio, VQF, Oggvorbis,AAC, APE. CDThe audio quality of the CD format is relatively high. So to speak the audio format, CD is naturally the leading pioneer. In most playback software, the "hitOpen file Type ", you can see the *.CDA format, which is the CD track. Standard CD format is 44.1K sampling frequency, rate 88k/Seconds, the 16-bit quantization b

damaged. Method 2 is fast and there will be no errors, unless the mmccard is really damaged. However, a computer and a card reader are required. [Bell] QD only recognizes three kinds of ringtones: WAV, Midi, MAR, and Mar. It is rare to use special software for conversion. Therefore, it is not commonly used, and WAV and Midi can be downloaded anywhere on the Internet, these two files are usually used!

Recently, many new people are asking: ape, flac which is better? Well, before answering this question, let's talk about how ape and flac came from. (Don't tell me that your ape and flac are converted to MP3 files.) To get lossless music, first, capture the CD file to your computer and change it to WAV. Some people may ask, will the sound quality be lost when the captured track is changed to WAV compared to

(2) lossy format, for data compression, after compression lost some data, such as MP3, WMA and other files. 1.WAV file WAV files are currently the most popular lossless compression format. WAV files are flexible in format and can store multiple types of audio data.

WAV uses a digital signal, it is to use a bunch of numbers to describe the original analog signal, so it to the original analog signal analysis, we know that all the sound has its waveform, digital signal is in the original analog signal waveform on every time at once "take the point", give each point to a value, This is "sampling", and then all the "dots" can be used to describe the analog signal, it is clear that the more points in a given time, th

If you want to know the relationship between the MP3 frequency, bit rate, bit rate, and sound quality, the higher the frequency, the higher the bit rate, the better the sound quality. It seems that most of the MP3 frequencies are 44100hz. The bit rate is 128,192. The frequency mentioned here is the sampling rate, which is usually 44100khz, because it is the standard of music CD.Every song is captured from Cd, converted into wav files, and then convert

1. The first line is the format of the music, which is .wav. If your favorite music is not the type of the music, you must first convert it. Fortunately, there are many conversion tools.2. The music size is limited.

For example, you want to change your own icons for your program, use some lively cursors to increase interest, play some sound and animation files, or use a program written by others to implement a function. We often want to put these resources directly in the EXE file to form a separate executable file, which leads to a problem of how to access and use
