Solution:


    you are missing the C-Shell (csh). Install it by below command:

    sudo apt-get install tcsh

How to find zero crossing rate using pyAudio

That's a lot of unnecessary multiplication. Using a Boolean comparison and running it through np.diff will probably be faster:

zero_crosses = np.nonzero(np.diff(audioData > 0)))[0]

What this is doing:

1. creates a boolean array of where the signal is above 0 (audioData > 0)
2. does a pairwise difference (np.diff) so locations of zero crossings become 1 (rising) and -1 (falling)
3. picks the index of the array where those nonzero values are (np.nonzero).

Then if you want the number of crossings, you can just take zero_crosses.size.

As a bonus you have the timings of all the crosses so you can do things like a histogram that shows where more crosses are happening in your time history.

Re: Find and replace through regular expression

Problem Statement

Find (ah0 0.25) and replace it with ((ah0))

Solution:

Use following regular expression

Find: \(([a-z][a-z][0-1]) 0\.\d+\)

replace: ((\1))

Find and replace through regular expression

Problem Statement

Find aa1 and replace it with (aa1)

or find ey0 and replace it with (ey0)

Solution:

Use following regular expression

Find:  ([a-z][a-z][0-1])

replace: (\1)

esignal.c:974: error: ‘ARCH’ undeclared (first use in this function)

Error: esignal.c:974: error: 'ARCH' undeclared (first use in this function)



Solution:

1. Open the HTKLib/esignal.c file in a code-friendly text editor. You can use Xcode, or my personal favorite TextMate 2.

2. Find and change the below lines:

   Change Line 974: if (strcmp(architecture, ARCH) == 0) /* native architecture */

   To: if (strcmp(architecture, "darwin") == 0) /* native architecture */

   Change Line 1184: ` architecture = ARCH;`

   To: ` architecture = "darwin";`

3. Now, let's build! Run make all in the terminal window
