NVIDIA - GPU - Control Commands - How to use nvidia-smi effectively. - Must read.

-
Dear Researchers/NVIDIA-Graphics Card users,
In this post I am going to share a command which will allow you to use NVIDIA-graphics card more efficiently. Many times we are faced with getting information such as who is using the NVIDIA-graphics card, how much memory is being used for a graphics card and whom to tell "Please kill your jobs I have something important coming up!!!"
The following command took me about 1.5 hours to create since there was no information on the internet on a command like this.
The command is long - So save it in your bashrc file with your favorite alias.
nvidia-smi && nvidia-smi pmon -c 1 | awk -F ' ' '{print $2}' | xargs -0 > t1 && export i=0; export l2="-"; while IFS='' read -r line;do if [[ "$i" -lt 2 || -z "$line" || "$line" == $l2 ]];then echo $i; else ps -p "$line" -o pid,vsz=MEMORY -o user,group=GROUP -o comm,args=ARGS | awk '{for ( x=1 ; x<=1 ; x++ ) { printf("%s\t",$x) } for (x=2;x<=2;x++) { if(NR>1) { printf("%13.2fMb\t",hr=$x/1024) } else { printf("\t%s\t",$x) } } for ( x=3 ; x<=NF ; x++ ) { printf("%s ",$x) } print "" }'; fi; i=$((i+1)) ;done < t1 && rm t1
Output will look something like this
Normal NVIDIA-SMI command and then for each individual command information as follows
PID MEMORY USER GROUP COMMAND ARGS

SOX - Sound eXchange - How to use SOX for audio processing tasks in research.

-
This article is part of the on-going Software for Geeks series. SoX stands for So und e X change. SoX is a cross-platform command line audio utility tool that works on Linux, Windows and MacOS. It is very helpful in the following areas while dealing with audio and music files. Audio File Converter Editing audio files Changing audio attributes Adding audio effects Plus lot of advanced sound manipulation features In general, audio data is described by following four characteristics: Rate – The sample rate is in samples per second. For example, 44100/8000 Data size – The precision the data is stored in.  For example, 8/16 bits Data encoding – What encoding the data type uses. For example, u-law,a-law Channels – How many channels are contained in the audio data.  For example, Stereo 2 channels SoX supports over 20 audio file formats. To get the list of all supported formats, execute sox -h from the command line. One of the major benefits of a command-line audio/mu

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 silence should be trimmed from the beg

Today we will learn How to get the duration of a file using ffmpeg 1. Format Container Duration - [This works for both Video and Audio Files - better to report numbers using this command] ffprobe -v error -show_entries format=duration \ -of default=noprint_wrappers=1:nokey=1 input.mp4     2. Video Stream Duration - [This works only for Videos]   ffprobe -v error -select_streams v:0 -show_entries stream=duration \ -of default=noprint_wrappers=1:nokey=1 input.mp4     Content author - https://superuser.com/questions/650291/how-to-get-video-duration-in-seconds
