I want to create any audio file with array of pcm, sample rate and number of channels.
The array size is about 15,000,000 in the range of 1 and -1.
I do not know much about audio file and just understanding what pcm is.
So, Could you give me any hints and keywords to make audio file with the data?
javascript audio wav pcm

new WAV(numChannels, sampleRate, 16, true, pcmData)will give you an object that can generate a binary blob with thetoBlob()method.

@PatrickRoberts It works! Thanks! If I have two array of pcm for each channel, how can I set them?

2-channel PCM data is interlaced, so the array you pass topcmDataneeds to have channel 0 sample 0, channel 1 sample 0, channel 0 sample 1, channel 1 sample 1, channel 0 sample 2, etc...
