Octave 'wavread' undefined

Question

I have GNU Octave 5.2.0, and I want to use it to analyze the IQ data in a wav file. This link describes a function called wavread which I can use in Octave, but when I run y = wavread(filename), I get this error message:

error: 'wavread' undefined near line 1 column 1

Why do I get this? My best guess is that wavread is deprecated for some reason and only exists in earlier versions. My other guess is that I have to install an extension to use wavread, but I didn't find a source that allows me to do this.

you can use [`audioread`](https://octave.org/doc/v5.2.0/Audio-File-Utilities.html#index-audioread) — Sardar Usama, Jun 24 '20 at 16:48
Audioread doesn’t give me as much information as wavread would — Daniel C Jacobs, Jun 24 '20 at 17:54
You are right about the deprecation, btw: https://www.gnu.org/software/octave/NEWS-5.1.html#deprecated-functions-and-properties — Tasos Papastylianou, Jun 24 '20 at 20:47
@TasosPapastylianou such as nbits. I suppose I can either make audioread work or install an older version of Octave. Thanks! — Daniel C Jacobs, Jun 25 '20 at 14:55
@DanielCJacobs no need to reinstall just for `nbits`, you can use [`audioinfo`](https://octave.org/doc/v5.2.0/Audio-File-Utilities.html) to get that. — Tasos Papastylianou, Jun 25 '20 at 16:28
@DanielCJacobs also, have a look at octave forge what other "audio" related functions there are. That "mulaclab" at the bottom [of this list](https://octave.sourceforge.io/list_functions.php?q=audio&sort=package) may be of interest to you — Tasos Papastylianou, Jun 25 '20 at 16:31

As discovered by @TasosPapastylianou, the wavread function is deprecated as of Octave version 5. Solution is to use audioread function.
