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 the toBlob() 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 to pcmData needs to have channel 0 sample 0, channel 1 sample 0, channel 0 sample 1, channel 1 sample 1, channel 0 sample 2, etc...

Run scheduled task as local user group (not BUILTIN)

Image
0 I am trying to run a scheduled task with User Group (not a single user). This is working fine when I in the field "when running a task, use the following user account:" insert BUILTIN User Group (for example: Administrators or Users). But when I try it with the created Local User Group (example: TestGroup) it is not working. The Users in the TestGroup are the same as in the Administrators group. What could be the problem? Are there some restrictions to the Created User Group compared to BUILTINUsers? scheduled-tasks taskscheduler windowstaskschedule share | improve this question asked Nov 15 '18 at 15:36 Far...
