Installation of Praat - Solve unable to hear sound issue quickly.

-
Praat is a software package for analysis of speech and get detailed information like pitch, spectogram, intensity and a raft of speech features needed in detailed analysis.

Praat is well recognized in the research of phonetics and linguistic.

Here's a link to the official praat website: - http://www.fon.hum.uva.nl/praat/

Let's get to issues faced while installing from the default package manager in Linux.

I had used sudo apt-get install praat on a Debian system.

The package manager installed praat successfully which was launched by typing praat from the terminal.

Launching was not an issue, however when I tried to play an audio file in wav format, there was no audio from Praat play command.

To check the setup of hardware tried to play the file from another player - banshee and the sound file worked just fine.

bt_audio_service_open: connect() failed: Connection refused (111)

The above message was displayed from the terminal screen while playing the audio file from Praat.

On googling found [http://ubuntuforums.org/showthread.php?t=1490237] that the issue was due to bluez-alsa package installed in system.

Uninstalled bluez-alsa package using synaptic package manager but still the issue still persisted where praat was not able to play the audio file.

Spend another few hours trying to solve the issue, but since nothing was being displayed from the terminal output.

Finally got the idea to uninstall and install again and this time with the package provided on the praat website.

Downloaded the tar file and unzipped it and typed ./praat from the extracted directory

Voila it worked fine!!!

Moral of the story: Don't try to use shortcut command of sudo apt-get install to get your work done. Keep an open eye for other solutions as well.

Sox of Silence - Original post - http://digitalcardboard.com/blog/2009/08/25/the-sox-of-silence/

The SoX of Silence SoX is, by their own definition,  the Swiss Army knife of audio manipulation. And no doubt it’s full of fun with slicing and dicing and playback and recording and filtering and effects capabilities. But SoX is a command line tool, which means obscure syntax and parameters in order to get things done. I’ve been trying off and on for months to try to understand the  silence  filter from within SoX, which allows one to remove silence from the beginning, middle, or end of the audio. Sounds, simple, doesn’t it?  Well, it should be. Below is the  man page for the  silence  filter : silence  [-l] above-periods [duration threshold[d|%] [below-periods duration threshold[d|%]] Removes silence from the beginning, middle, or end of the audio. Silence is anything below a specified threshold. The above-periods value is used to indicate if audio should be trimmed at the beginning of the audio. A value of zero indicates no...
