[update] node-red-contrib-sox-utils : beta

Continuing from

Bump to 0.2.6

I added the possibility to convert raw audio files and buffers with the convert node. For this to work you need to include the necessary audio header information that sox needs to process raw audio as msg properties. The format of this is described in the nodes info panel. This can also be used to add wav headers or process raw audio to be played by the play node by routing it through the convert node first.
I will look to publish the node to npm before the end of the year.

Update to 0.3.0

  • this update adds two major feature enhancements to the nodes:

    • The record node can now record from a stream of raw audio chunks that are send to it. Just select the option from the source dropdown and the node automatically changes to input mode and a menu section where you have to enter the necessary header information for the audio becomes available. This can be very useful if you are streaming the raw audio from another machine or are you using some other way to receive the stream in nodered.
    • the play node has also gained the functionality to playback a stream of raw audio, for example to listen in on levels while recording or establishing a Walkie-Talkie function between to nodered instances. This feature is exclusive to the normal file playback options. So these become unavailable if the stream playback option is selected. Similar to the record node a header section will become available if selected and needs to be filled in for the stream processing to work.
