Haha, I understand your point, but no I'm not a ♥♥♥♥♥♥♥ guitarist forced into bass, I've always mained bass and dabbled with guitar. The metal bassist example is far from the Victor Wooten, Jaco Pastorious, etc. material I play :)
Those superior interfaces that you have are superior for recording sound. But that is designed for Analog Sound going to a sound file. And that Superior Sound may just be too much information for the game to handle.
RS requires that sound to be converted to Digital which the Realtone cable does...
Every input of a soundcard does just that: convert an analog signal to a digital one. The Realtone cable is just an ADC between your guitar and the USB of your PC, an USB soundcard with just one input and no output. The amount of information is completely determined by sample rate and bits. RS wants 48kHz/16 bit, something every ordinary soundcard can handle just fine, no matter how good it is. Sorry to say that, but your comment is utter nonsense. The only difference between the line in of a soundcard and the Realtone cable is impendance. So, when you use the line in of a soundcard you'll get impendace mismatch, which can cause note detection to fail more often. This could be worked around by using a DI box between your guitar and the line in. The only reason RS does not support this is because it would be a hell to support for the devs because of the plentitude of differing devices out there. It has nothing to do with amount of information or the cable being anything special.
Am I positive on what exacly that circuit does? No. Despite me having gone to college for Robotics... and still mess with circuits as a hobby... I cannot cut open the unidentified chips and tell you exactly what they do... So what I have is a logic based theory based off of what I can tell from the circuits... Which is no less valid as your theory....
So we can jump back and forth again calling each other idiots. And how much nonsense each others comments are.. or we can get back to the point of The Cable Is Required.
I am positive about what the cable does. It's detected as microphone, you can use some recording SW to record your guitar with it, it has sample frequencies and a bit rate to select in the settings. It's just a soundcard. No, your idea is not logic, it's nonsense. Building the note detection in HW would be totally crazy and of no use at all. I don't care about you going to a college of robotics. You clearly have no clue about how a program like RS works, you don't know anything about sounddevices (this is based on the fact that you seem to think a "recording soundcard" is designed for "Analog sound going to a soundfile", which is as wrong as it can get.) I don't call you an idiot. I don't know you. But I call your comment nonsense, because it is. Simple.
Incorrect. It's simply a sound card. I am a qualified audio engineer and have knowledge about game design and coding.
Any recording input interface (3.5mm input on your pc, external sound cards, Rocksmith RT Cable) is an analogue to digital convertor. Analogue sound waves travel through your guitar cable into these interfaces, where the A to D conversion happens inside the electronic circuitry. The signal value (voltage/current) is converted into 0s and 1s, which is then sent to and decoded by your computer. During this part, the game software uses information to match the frequency (note) of the music you're playing to the 'guitar hero fret tab board'.
I had to resort to using a crack here to make my PC internal sound card work (unfortunately I couldn't route my 2i4 to the game using the guide I found). But yeah, to answer this, the RT cable is simply a sound device, any fancy decoding is done in the game software on your PC.
You are a qualified Audio Engineer with knowlege about game design and coding... and you cannot afford to spend $50 on a cable? Really?
You have not purchased the cable and "had to resort to using a crack"... but you have all the answers and know exactly what it does? Impressive..... Good luck with that crack...
Lol you definitely don't know the life of an audio engineer. Money definitely doesn't grow on trees. It's also the fact I'd prefer to use my higher quality gear for better sound.
The crack is working just fine, it's just unfortunate they couldn't offically support external devices, at least for those who have the capability to do so.
I never said the "note detection" was done in the cable. Which is why all of your comments are nonsense.
I said the cable converts the sound from the guitar (vibrations in electrical signal) to a digital format that "makes it easy" for the game to detect the notes.
You say it is "just a soundcard". What exactly is a soundcard? Something that translates digital signals into electrical vibrations to create sound from a speaker... or the reverse something that captures and translates electrical vibrations from a microphone, or guitar in this case, to a signal that the software on the computer can recognize. So, yes it is a type of soundcard. My statement did not say it wasn't. Only that the conversion was done in a specific way to allow the game to detect the notes.
You say it is "just a soundcard".... which means that you believe that all soundcards are the same... If they were the same then you cannot possibly state that your soundcard is superior... Because if your soundcard is superior, then obviously there are differences in how the electrical vibrations are captured. Which completely negates any arguing stance that you have with it just being a soundcard.
You say it is detected as a Microphone... Exactly... It does not have a software package (Drivers) doing the conversion of that signal. All other soundcards have drivers that you install... This one just says "Hey, I am a Microphone.. nothing special"
You suggest that the only difference is impedance... now yes, impedance is one factor. but not the only one.
Now... at minimum... RS provided a great cable for pluging your guitar into your computer for only $50.... Which for some reason, an "Audio Engineer" can't make enough money to afford... How much did all of your superior soundcards cost?
People have had issues with the crack.... you have a piece of software in between your sound device and the game that is making changes... Those changes take time, and software is slower than hardware.... and you will see those issues as you progress.
I get it... money is tight and you want to play now... so for the best experiance, save up and buy the cable... then reinstall without the crack.
That statement is just showing the difference.... Is the soundcard trying to capture every single up and down peak of the guitar? Or is it trying to capture just enough to recognize the note being played?
The higher priced recording devices are designed to capture as much of the vibration as possible for the best sound output... As many 1's and 0's as possible to map out every single change of that sound.
Too much information can be a bad thing for a game trying to detect notes. Requiring the game to filter that signal to get at what it needs. Requiring more code. More time. more clock cycles.... etc... causing lag. And if you do not understand that, then you clearly have no clue how a program like RS works.
OMG. Sample rate is 48kHz, bit rate is 16bit, the amount of data captured is determined by these values. No matter if it's done by the cable or some other device, it's always the same amount. Get a clue, really. You don't understand even the basics of sampling audio. Amount of code does not change at all, BTW. You do Fourier transforms. The code to do them does not change at all, just because you drop information or use smaller sample rates. All you introduce by removing information of the signal is noise, which you have to filter out afterwards. See? In fact. it's the opposite from what you state. We can discuss this as long as you like, to any level of detail you want. I did a lot of low-latency audio programming. I wrote my own effects using LADSPA, I used libfftw to do Fourier transforms in many of my programs. I know the theory behind them. I know how RS works in theory. I even could write a poor mans version of it myself. Maybe, just maybe, you'll learn something in the end. But hey, better keep calling me clueless, because you went to a college of robotics.
