Sox combine files

If this function is not explicity called the input format is inferred from the file extension or the file's header. Should be the same as what the file extension would be, for ex. If None the sample rate is inferred. If None, the number of bits per sample is inferred. If None the number of channels is inferred. Sometimes needed with file-types that support more than one encoding type. Each effect plugin has its own syntax, so refer to the man page for details on how to invoke each one.

Effects can be daisy-chained in one command, at least to the extent that you want to combine them. In other words, there's no syntax to apply a flanger effect only during a six-second fade-out. For something that precise, you need a graphical sound wave editor or a digital audio workstation such as LMMS or Rosegarden. However, if you just have effects that you want to apply once, you can list them together in the same command.

This command applies a -1 gain effect, a tempo stretch of 1. To join or concatenate files into one, provide more than one input file in your command:.

In this example, output. If you want the two tracks to play over one another at the same time, though, you can use the --combine mix option:. Imagine, however, that the two input files differed in more than just their codecs. It's not uncommon for vocal tracks to be recorded in mono one channel , but for music to be recorded in at least stereo two channels.

SoX won't default to a solution, so you have to standardize the format of the two files yourself first. Options related to the file name listed after it. For instance, the --channels option in this command applies only to input. This means that the position of an option is very significant in SoX.

Should you specify an option at the start of your command, you're essentially only overriding what SoX gleans from the input files on its own. Options placed immediately before the output file, however, determine how SoX writes the audio data. To solve the previous problem of incompatible channels, you can first standardize your inputs, and then mix:.

SoX absolutely requires multiple commands for complex actions, so it's normal to create several temporary and intermediate files as needed. Not all audio is constrained to one or two channels, of course. If you want to combine several audio channels into one file, you can do that with SoX and the --combine merge option:.

It only takes a minute to sign up. Connect and share knowledge within a single location that is structured and easy to search. I have two audio-files and want to mix them with SoX using the -m, --combine mix option. Both files have the same bpm, but not the same length, meaning I need to loop one file, but not the other. Does anyone on here know if possible how to do this? I managed to create a looped file with sox by using the repeat option, but I can not use this option only on one input file,.
