Changing the Sampling Size of a Sound File Use the following example, to change the sampling rate of file ‘old.wav’ to 16000 Hz, and write the output to ‘new.wav’ $ sox old.wav -r 16000 new.wav 9. To change the sampling rate of a sound file, use option -r followed by the sample rate to use, in Hertz. Changing the Sampling Rate of a Sound File If SoX is invoked as ‘rec’ the default sound device is used as an input source. You can also use rec command for recording voice. dev/dsp file works for both playing and recording sound samples. Reading the device activates the A/D converter for sound recording and analysis. dev/dsp is the digital sampling and digital recording device. ‘play’ and ‘rec’ commands are companion commands for sox. You can also use play command to hear the song in reverse without modifying the source file as shown below. This will reverse the file and store the result in output.wav $ sox input.wav output.wav reverse Use the ‘reverse’ effect to reverse the sound in a sound file. Syntax :play options Filename audio_effects You can also use play command to play the audio file as shown below. The following command plays the file music.wav: Option -t specifies the type of the file /dev/dsp. Playing a sound file is accomplished by copying the file to the device special file /dev/dsp.

This example explains how to play an audio file on Unix, Linux. Sox provides the option for playing and recording sound files. The -e flag tells sox not to generate any output other than the statistical information. The stat option can provide lot of statistical information about a given audio file. In the following example, the 1st command (-0.5) will be louder than the 2nd command (-0.1) $ sox -v -0.5 srcfile.wav test05.wav Lower Negative number will get more soft. If we need to lower the volume on some files, we can lower them by using negative numbers. Increase Volume $ sox -v 2.0 foo.wav bar.wav Decrease Volume Option -v is used to change (increase or decrease ) the volume. Increase and Decrease Volume Using Option -v The command below will extract first 10 seconds from input.wav and stored it in output.wav $ sox input.wav output.wav trim 0 10 3.

Plus lot of advanced sound manipulation features.It is very helpful in the following areas while dealing with audio and music files. SoX is a cross-platform command line audio utility tool that works on Linux, Windows and MacOS.

The 8-bit data and the 16-bit data don't match up at all as I expected.This article is part of the on-going Software for Geeks series.

In the process of trying to figure out the problem, I used QuickTime Pro to do the conversion and compared the original 16-bit file against the converted 8-bit file. wav file header to reflect the change from 16-bit to 8-bit.The resulting file contains loud random noise. after this, I output only the first half of the byte array Is this correct? Assuming it is, I wrote the following simple code, but it doesn't work. I understand that to convert 16-bit PCM into 8-bit PCM, I only need to discard one byte from each sample.
