Given the string (or any length string with an even-number of word pairs): "12345678"
How would I swap adjacent "words"?
The result I want is "34127856"
As well as, when that's done I need to swap the longs. The result I want is: "78563412"

-mtimeit -s'import swa' 'swa.withre(swa.s)' 78563412 78563412 10000 loops, best of 3: 42.2 usec per loop usec per loop
...and ....
I want to swap "byte pairs", not the order of the bytes.
Which is my original desired result.

Also, what is the byte order expected by the wav file format for 16 bit....
Channels; // Number of Channels: 1=mono, 2=stereo SInt32 sampleRate; // Sample Rate: samples per since it's treating your lengths as pointers right now.

This is very odd
I'm reading some (admittedly very large: ~2GB each) binary files using numpy libraries in Python. I'm using the:
thingy = np.fromfile(fileObject, np.int16, 1)
method. This is right in the middle of a nested loop - I'm doing this loop ...

Although it's hard to say without some kind of reproducible sample, this sounds like a buffering.

Hello community. I have an interesting question today.

Then you can use a tool like "hexdump" to dump for an 8-bit stereo file each sample will be arranged as follows.
U for unsigned linear, and -1 for 1 byte per sample.

I have had success in my testing to run DMA datalogging on my Evo IX.
The usual MUT protocol only runs at 150-180 samples per second, and they are of limited resolution because they are only bytes whereas the internal ECU variables are 2 bytes. In a low...

I think.
A second at 4800 baud is what I was really asking? Depends on how many bytes each sample is.
