Usually, how do you deal with sound files in the design of multimedia software? Use the API function sndPlaySound provided by Windows to implement WAV file playback? However, have you ever encountered this situation: when the WAV file is larger than the available memory, the sndPlaySound function can not play!!! So, how do you use MCI to play large audio files?

-dual channel. When two channels exist, each sample contains audio data of the left and right channels. Therefore, the data of the two channels isStaggered ArrangementOf; (1) Wave format WAVE is a sound file format developed by Microsoft. It is used to store Audio Information Resources on the Windows platform, with the file suffix *. wav. It supports multiple co

to appear abstract point, for example: Suppose that a wave is sampled 8 times, the sample points corresponding to the energy value of A1-A8, but we only use 2bit sample size, the result we can only retain 4 points in the A1-A8 value and discard the other 4. If we do a 3bit sample size, we just record all the information for the next 8 points. The larger the value of the sample rate and sample size, the more the recorded waveform is closer to the original signal.2. Lossy and LosslessAccording to

objectively reflects the accuracy of the digital sound signal's description of the input sound signal. 16Bit indicates that a value is marked with a 16-bit (2-byte) computer.Number of channels: refers to the number of speakers to support different sounds. The common ones are mono and two-channel.Bit rate: The number of bits (bit) transmitted per second, equal to the sample rate * Sample bit number, in bps (bit per Second). Sample audio has a bit rate

WAV (waveform audio format) is a sound encoding format developed by Microsoft and IBM that complies with the riff (Resource Interchange File format) files specification for saving the audio information resources of the Windows platform. Widely supported by the Windows platform and its applications, it is also one of the specified specifications commonly used by i

PCM (pulse codemodulation----Pulse Code modulated recording). The so-called PCM recording is the sound and other analog signals into the symbolic pulse column, and then recorded. PCM signal is a digital signal composed of [1], [0] and other symbols, without any coding and compression processing. Compared with analog signal, it is not susceptible to the clutter and distortion of the transmission system. The dynamic range is wide and the effect of sound quality can be very good.

1 Perl script On the Peking University Chinese forum, a netizen asked how to play the PCM data from the end. I used to encounter 8 K sampled PCM data at work. At that time, I was not clear about the wav file format. The Perl module has an audio: WAV module that can write wav files, a Perl script is written: use
