This is a project that I have been working on for several months off and on.
It's a simple "What You Hear" MP3 @ 320Kbps and WAV audio recorder.
- LoudMax, a Gain Controller and Look-Ahead Limiter
- Auto Shut-Off after one minute of silence
- Side-by-Side Simulated LED Meter
- Running Time Counter
It started off being a large project, but I eventually stripped it down to its
bare essentials because I came to realize that it would be very difficult to
deal with every sound card and every way a PC is set up for audio. It would
have been a nightmare that I was not willing to go through.
This project contains the most up-to-date BASS.dll v.188.8.131.52 - December 17, 2019.
All BASS Dll's are 32bit. Those and the needed UDF's are included in the zip file.
I will try to explain how it works in the next post.

In this post I take the opportunity to show the awesome capabilities of AutoIt and its libraries. My open source project Peace is a long running AutoIt based app located on SourceForge. It provides users with a system-wide equalizer and effects machine. It's an interface using the power of Equalizer APO, an audio processing object software. Peace has been download over 1,100,000 times by various kind of users. Amongst others it gives them possibilities like these:
Hearing impaired - Amplify the gain of frequencies which are impaired. Home Theatre - Create Equalizer presets for watching movies and listening to music. Music lovers & audiophiles - Create presets for listening to music on their high quality speakers and headphones. Gamers - Enhance frequencies to get an edge over other gamers. Headphones - Improve the sound quality of cheap headphones and get the max out of expensive ones. Bass lovers - Boost low frequencies for extra bass. Voice - Make a microphone sound better and improve the voice, for instance for YouTube usage. Low audio - Boost low audio of an input source to a comfortable level. This list covers the main needs of the Peace user. Many people have contacted me over the years asking for new features and telling me how they use Peace for their (sometimes specific) needs. I was able to use AutoIt and its libraries for all of their needs. So what are the main features of Peace?
Equalize your computer audio by using up to 31 sliders. Support of equalizing 9 speakers : left/right, center, subwoofer, left/right rear, left/right side. Per slider a filter can be chosen such as peak, low/high pass, shelving. The graph windows shows your equalization so you see exactly what you're doing. Apply an effect such as crossfeed simple/Jan Meier/Chu Moy, stereo balance, bass/treble, upmix/downmix, channel routing. Save presets (called configurations) and activate by mouse click, hotkey, desktop shortcut or Peace system tray. Select a target device to equalize, microphone as input can also be equalized. Automate: you can let Peace automatically activate presets on a switch to another device and another process. Peace is available in these languages: English, Czech, Deutsch, Français, Italiano, Nederlands, Pусский, Українська So who am I? I'm a Dutch programmer who happens the stumble upon AutoIt 5 years ago and created a small Equalizer interface app of less than 400 program lines with it. Nowadays Peace has grown to more than 17,000 lines as many features were added. Although Peace is open source, the program code isn't of the best possible quality. The reason being that I didn't expect it to become so popular. It caught me by supprise. I've created a Library of functions called Pal (link to forum post) which quality is up to the AutoIt community standard as counterpart to the Peace program code.
I want to state here that AutoIt is a mature program language as Peace obviously shows. I wish it to be used more extensively for professional or semi-professional apps. In my view AutoIt deserves a place amongst the major programming languages for Windows computers.
I created a FMOD UDF (x86 / x64 compatible) whereas the DLL calls are done from memory directly!

In the zip archive you can find 6 examples.

If you have created additional examples, feel free to post it here.
I ran across a topic while researching the BASS UDF...
https://www.autoitscript.com/forum/topic/155845-carpenter-needs-help-performing-serious-surgery-on-audiometer2/ and then remembered another topic...
https://www.autoitscript.com/forum/topic/121624-sound-level-sampling/ which got me to thinking as to how I could get the first topic to go LIVE without the need of loading an mp3.
This will accept any LIVE AUDIO INPUT.
Be sure to read this post if you have trouble with it...
https://www.autoitscript.com/forum/topic/121624-sound-level-sampling/?do=findComment&comment=1400178 Also, read the comments I made in the script, so you will know how it will react to LIVE INPUT streams.
