Hi Corona688...

Files are not needed if you are using SOX and piping.
An ultra simple string piped into sox without the need for files at all...
But I am NOT using SOX here but the very, very limited afplay audio player for OSX.
afplay cannot replay raw files only a few basic formats of which .WAV is one.
Code:
#!/usr/local/bin/dash
square="    ~~~~"
for n in 1 2 3 4 5 6 7 8 9 10
do
	square=$square$square
done
echo "$square" | sox -b 8 -c 1 -e unsigned-integer -t raw -r 8000 - -d

Results:-
Code:

Done.

Just change the sample speed inside SOX from 8000 to anything you like within limits.

NAME
Aserver - start the audio server SYNOPSIS
DESCRIPTION
The command starts the HP-UX Audio server, which can run on a system with audio hardware. See Audio(5) for information about which systems have audio hardware. The option forces the starting of the Audio server; this option is only needed if the Aserver has problems starting. The Audio Server Before using any audio tools such as the the system or X station must be running two audio server processes, called On a Series 700, the Remote Procedure Call daemon must also be running. Normally, the Aserver processes and start automatically when the system is booted. If problems occur on an ENTRIA or ENVIZEX X station, see the X station owner's manual. On a Series 700 Audio hardware, first check if is running. Type the following: If it is running, you see a line similar to the following. If it is not running, see HP 9000/DCE documentation for information on restarting it. If is running, verify that the Aserver is running. Type: If the Aserver is running you will see lines similar to the following, which indicate the presence of the two Aserver processes: If it is not running, become root and restart it as follows: If it fails to start, reissue the command with the option: Using Audio over the Network From a workstation, you can also use the Audio Editor and Control Panel over the network. However, the remote system is where the actual playback and recording occur. The local workstation (or audio client) can be any Series 700 system. The remote system (or audio server) can be a Series 700 or an X sta- tion with audio hardware and must have the Aserver processes running. If the server is a workstation, it must also allow access from remote clients (see asecure(1M)) and must have running. To make the system an audio client, set the variable by modifying the file as follows: Korn and POSIX Shells: C Shell: For system_name, identify the workstation or X Station running the Aserver. If the variable is not set, the Audio Library attempts to use to the Aserver on the system defined by the variable. If neither nor is set, the Aserver on the local machine is used. DEPENDENCIES
The Audio Server must run on a system that has audio hardware. Note that HP-UX for the 8MB 705 System does not include audio software. AUTHOR
