这里,先获取原文件的AudioFormat,然后根据这个旧的AudioFormat创建一个新的AudioFormat。注意,这里新的AudioFormat除了Encoding发生改变,sampleSizeInBits也要改成16,相应的frameSize也要发生变化。(frameSize表示一个Frame占用的字节数,也就是声道数) 构建完了新的AudioFormat,通过AudioSystem.getAudioInputStream(newForma...
We call this "bits per second" value as the audio file's bit rate. We can express bit rate equation as: bit rate = bit depth * sample rate Audio bit rate values range from as low as 32 kilobits per second (kbps) to as high as 18 megabits per second (Mbps). Spotify uses values...
Set the bitrate property: The bitrate, in bits per second, of the output encoded audio. AudiowithChannels(Integer channels) Set the channels property: The number of channels in the audio. AudiowithLabel(String label) Set the label property: An optional label for the codec. ...

BitsPerSampleGets the bits per sample of the audio. BlockAlignGets and sets the block alignment in bytes. ChannelCountGets the channel count of the audio. EncodingFormatGets the encoding format of the audio. SamplesPerSecondGets the samples per second of the audio. ...
Those individual samples vary in the amount of information they have. Bit depth is the number of bits in each sample or how information-rich each of those 44,100 pieces of audio is. A high sample rate and a higher bit depth both increase the amount of information in an audio file and ...
bitrate:输出视频的比特率,也即码率BPS(Bits Per Second),指每秒传送的数据位数 audio:可以为True、False或文件名,如果True且剪辑附加了音频,则音频将作为视频的音频保存,如果为False则不保存音频,如果为音频文件名则将此音频文件将作为视频的音频 audio_fps:声音的采样频率 ...
