I want to read the data of an 8bit wav file using textPad, I know that the data is located at the 44/46th byte, but I am having problems reading it.
I have that code:
52 49 46 46 F8 37 01 00 57 41 56 45 66 6D 74 20
12 00 00 00 06 00 01 00 40 1F 00 00 40 1F 00 00
01 00 08 00 00 00 66 61 63 74 04 00 00 00 C6 37
01 00 64 61 74 61 C6 37 01 00 D6 D4 56 54 D5 56
56 51 D4 D3 D0 D6 54 57 D4 54 57 51 57 D0 D3 D1
etc.
The part in bold is the data of it.
The problem is when i read it in sndfile using sf_read_int
I get in the buffer the following values:
3670016 1572864 -3670016 -1572864 524288 -3670016 -3670016
etc
How am I supposed to read the data in the wav file? What is the equation or 'relationship' between the numbers i got in sndfile and the data in textPad?
Oh and one more thing, if i switch the reading to sf_read_float
instead of int i get values between -0.0001 and +0.0001...
Any idea what's happening, the writing and data processing is very good but I don't understand what's up with these values.
Thank you.
Okay so i found out that the wav file is encoded and libsndfile takes care of it without any intervention. That caused the "unequal" values.
