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 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.
This is my latest project, which I have been working on for a few days now, so this is kind of hot off the press. However, in reality, I have been working on some element of this for years. Some of you may remember a huge project of mine (Audio DVD Producer + Chat Blog Screenshots) that I worked on a good while back? Well, this one is very much related, and very much simpler in scope. That other project by the way, has been basically stalled for a good length of time now. Not because I never finished it, but because the end result was not as great as I hoped. I may share the files for it one day. I may even start working on it again one day, though this latest project kind of makes much of it redundant for my aims.
Anyway, this project. I have a good bunch of DTS-CDs, from same or other sources (i.e. DVD). You can read more about what a DTS-CD is here, but the short of it, is that you cannot play them on a normal CD player, as you will just get noise. Many if not most DVD or Blu-ray players can play the embedded DTS data in the otherwise empty CD tracks. Further to that, a DTS-CD is essentially a compressed PCM or WAV file for all intents and purposes ... to keep things simple. So a 6 Channel (5.1) track takes up roughly the same amount of bytes as a normal stereo CD track ... so 6 channels for the price of 2.
Up until recently, the best device for me to play the DTS-CDs on, as CDs, is my PS3. It plays them faithfully (reader issues aside) and has nice visuals. It is also my most convenient DVD/Blu-ray player, so a heap of hassle to play on one of my regular players, and not much success with the Xbox 360 ... at least with burnt backup copies.
DTS-CDs are also kind of old school, and been superseded by the more superior lossless DVD Audio, Super CD and now Blu-ray Audio discs. That kind of makes them rare now and essentially irreplaceable, so being a wise man, I store them safely and only play backup discs.
Playing discs though is kind of limited, and to be honest a pain, as my PS3 spits the dummy on some days, with the reader not being what its should be ... or perhaps poorly calibrated. So for a long time now, I have been wanting to use the backup files instead. Unfortunately, while I can play them fine on my PC (foobar2000 + DTS plugin), that is not where I want to listen to them. Until recently, neither my NeoTV 550 hardware player or my Laser one, have been very good at playing the files, and the PS3 even worse with its lack of file support. Back when I first investigated all this, and tried a bunch of things, and didn't yet have the Laser (4k Android) player, I did attempt to go the FLAC route. However, I was left unsatisfied, as my NeoTV did not support CUE files and M3U playlist files are a bit of a hassle ... and no help, when I have a single album file with cue index points for each track ... which many of my DTS-CD rips were ... especially for albums that have one track running into the next ... live albums too. The other issues for me with FLAC, were the artwork (album cover) and TAGS (details for each track - Title, Artist, Album, Year, etc), which I could not get to work.
So, moving forward to recently. I played a DTS-CD on the PS3 the other day, and if there is one things I hate, it is a playing issue when I am in the midst of enjoying a nice piece of music. The PS3 is not very forgiving and just aborts play. I am not very forgiving of the PS3, so decided to investigate FLACs again. Now perhaps something has changed, since I last tried ... or I just wasn't on the ball. Anyway, to cut a long story a bit shorter, I loaded a DTS WAV file in foobar2000, and ripped it to a FLAC file. I then tried that file on my NeoTV 550 hardware player, and it played fine ... and some tags were visible, which surprised me. So I thought it was worth looking into further. I also tried the file on my Laser hardware player, with the Kodi (XBMC) Android app, but alas, while the Tags and Artwork worked well, all I got was noise ... and same for every other app I tried.
Now don't ask me why I thought to try FLAC on its own, using the FLAC Frontend program initially, but I did ... and it recognized the tracks as 5.1. With foobar2000, I'd selected the decoder for DTS files when converting to FLAC, as I thought it was required. I hadn't at that stage used flac.exe by itself, but I decided to investigate the TAG command-line options and also noticed you could embed a picture, which I was keen as mustard to try. So I set up a BAT file and gave it a whirl.
Now the results on my NeoTV 550 hardware player, were brilliant - Sound, Tags and Artwork were as I wanted. I decided to update Kodi at that point. Then, I tried my Laser hardware player again, but still no joy. I then did some online research and read about how to get it all working. Alas, I had mixed results. The foobar2000 ripped file worked, but the one I did with the BAT file did not. Not being keen to rip everything via foobar2000 menus, and wanting to code a quicker batch solution myself, I first attempted to see what command-line options I could use for foobar. That was a dismal failure, so I then revisited some of the programs I had used way back when with DTS WAV based files, and eventually discovered that 'valdec.exe' from the AC3Filter tools collection, gave the compatibility I needed. So I put my WAV or DTS files through that program first, then converted them to FLAC.
Now the files played with DTS surround sound, on both my hardware players. They also play gapless, so I split album length files into separate track files, which avoids the CUE and M3U issues. That said, a joined M3U file for something like a (separate folders) double album, plays great with Kodi.
So of course, I just had to whip up a program ... with drag and drop of course.
And that program has steadily been growing & changing, and is where I want it now, at v1.5.
Screenshots further below.
Most programs (if not all) can be obtained from VideoHelp, but here are some alternative sites to source them. The 'flac.exe' program is definitely required, and 'valdec.exe' if you want maximum compatibility support for a wider range of players.
[valdec.exe] [found in the AC3Filter tools collection]
http://www.ac3filter.net/wiki/AC3Filter_tools (Info only, downloads no longer work)
If The Wayback Machine options fail, then go to VideoHelp (maybe go there anyway).
NOTE - The AC3Filter site has loads of information, which could help you enable other players aside from those below.
PC = foobar2000 + DTS plugin component.
Android Device = Kodi (XBMC) app with DTS etc enabled with passthrough.
NOTE - foobar2000 with plugin, will play even those not processed with 'valdec.exe'. My 'NeoTV 550' hardware player does the same. My 'Laser' (Android device) with Kodi just emits noise with the FLAC files, if not processed with 'valdec.exe'.
RECOMMENDED DTS-CD RIPPERS
This one of mine tells you a lot more about DTS-CDs, including ripping or burning.
P.S. I made a brilliant discovery today. Whereas in the past, with PS3 etc, I could not listen to my DTS-CDs via my Surround Sound Headphones, I now can with these files. So it is well worth playing those CDs as files, just for that benefit alone. Overall though, I have future proofed my collection.
This file includes all the source codes and a compiled .exe version of zPlayer, which is a stand-alone, simple, intuitive and easy-to-use, yet fully functional audio player. I made this to suit my purpose and you can tweak it to your taste as the source code is only about 1000 lines which are very much readable. This player has the following functions:
- Play back all formats of audio files which can be palyed back by the Windows Media Player in your computer
- Graphical player similar to embedded Windows Media Player
- Forward, backward, pause, repeat, shuffle funtions
- Increase/decrease/mute sound volume
- Change folders and create playlist for all audio files in that folder and its subfolders, and support for manually-made playlists
- Save play-back environment when terminating and resume that environment when restarting
- With one click, you can see DuckDuckGo search results for the file being played back
- With a double-click, you can play back an item in the playlist
- Search strings in the playlist
- Option to see long file names including folder names
- Resize the playlist window, and restore it to its default position
- Very small footprint: very low CPU and memory usage, with only about 1MB when compiled
- You can even hide all the windows and manipulate the player with hotkeys only
