NAME

       gr_plot_psd_c - plot power spectral density using GNU Radio

SYNOPSIS

       gr_plot_psd_c: [options] input_filename

DESCRIPTION

       Takes a GNU Radio binary file (with specified data type using --data-type) and displays the I&Q data versus time as well as the power spec-
       tral density (PSD) plot. The y-axis values are plotted assuming volts as the amplitude of the I&Q streams and converted	into  dBm  in  the
       frequency  domain  (the	1/N  power adjustment out of the FFT is performed internally). The script plots a certain block of data at a time,
       specified on the command line as -B or --block. The start position in the file can be set by specifying -s or --start  and  defaults  to  0
       (the start of the file). By default, the system assumes a sample rate of 1, so in time, each sample is plotted versus the sample number. To
       set a true time and frequency axis, set the sample rate (-R or --sample-rate) to the sample rate used when capturing the samples.  Finally,
       the  size  of  the FFT to use for the PSD and spectrogram plots can be set independently with --psd-size and --spec-size, respectively. The
       spectrogram plot does not display by default and is turned on with -S or --enable-spec.

OPTIONS

       -h, --help
	      show this help message and exit

       -B BLOCK, --block=BLOCK
	      Specify the block size [default=8192]

       -s START, --start=START
	      Specify where to start in the file [default=0]

       -R SAMPLE_RATE, --sample-rate=SAMPLE_RATE
	      Set the sampler rate of the data [default=1.0]

       --psd-size=PSD_SIZE
	      Set the size of the PSD FFT [default=1024]

       --spec-size=SPEC_SIZE
	      Set the size of the spectrogram FFT [default=256]

       -S, --enable-spec
	      Turn on plotting the spectrogram [default=False]

play(1) 						      General Commands Manual							   play(1)

NAME

       play - play any sound file to audio device

       rec  - record audio to any sound file format

SYNOPSIS

       play [fopts] infile [effect]

       rec [fopts] outfile [effect]

DESCRIPTION

       This manual page briefly documents the play and rec commands.

       play  and  rec are programs that allow you to play and record different types of sound files from the command line.  They are front ends to
       the more general sox(1) package.  Normally, the play command will automatically detect the type and other parameters of the  soundfile.	If
       it can't do so, the parameters can be changed through options.

OPTIONS

       A summary of common options are included below.	For a complete description of options and their values, see the sox(1) man page.

       -c [channels], --channels=[channels]
	      Define the number of channels in the file.

       -d [device], --device=[device]
	      Specify a different device to play the sound file to.

       -f [format], --format=[format]
	      Specify bit format of the sample. One of s, u, U, A, a, or g.

       -r [rate], --rate=[rate]
	      Specify the sample rate of the audio data (samples per second).

       -s [size], --size=[size]
	      Specify the width of each sample.  One of b, w, l, f, d, or D.

       -t [type], --type=[type]
	      Specify audio file format to use.  Useful if it can not be automatically determined.

       -v [volume], --volume=[volume]
	      Change the audio volume

       -x , --xinu
	      Reverse the byte order of the sample (only works with 16 and 32-bit data).

       -h, --help
	      Show summary of options.

       --version
	      Show version of play/rec.

       Description of effects are described in the
	      sox(1) man page.
