vb.net - Convert audio doubles to bytes -

i dealing raw pcm audio data (the audio data of pcm file without header).

this data provided me in form of vector of double.

i pass data function, , function expects audio data in form of byte vector.

i tried

    dim nbytes() byte = ndoubles.selectmany(function(d) bitconverter.getbytes(d)).toarray() 

but wouldn't give expected results.

i guess have deal conversion manually, unsure how should done.

can help?

thank you.

since required format other function 16-bit, 48 khz, same source data, it's simple case of converting source array of short, serializing byte array.

the problem code suggest first step missed, serializes double array. however, can re-use second step. so, can like:

    dim nshorts() short = new short(ndoubles.length - 1) {}      = 0 ndoubles.length - 1         nshorts(i) = convert.toint16(ndoubles(i))     next      dim nbytes() byte = nshorts.selectmany(function(s) bitconverter.getbytes(s)).toarray()
