The YMa. OPN2is a sound chip developed by Yamaha. The YM has the following features: [3]. However, its sixth channel can act as a basic PCM channel by means of the 'DAC Enable' register, disabling FM output for that channel but allowing it to play 8-bit pulse-code modulation sound samples.

Additionally, because of the reduced dynamic range of the built-in DAC, additional distortion may be generated when playing sounds with a very high volume. The YM[3] a. It is not a direct, drop-in replacement for the YM however, as the sound outputs have higher impedance. The YMFa. From Wikipedia, the free encyclopedia. FM synthesis sound chip by Yamaha.

Thankfully, as ofhe explains that most of these operations are now being shut down and moved into an industrial park where the work can be done in a less polluting manner. The next thing that [David] dives into is how these remarked chips can be spotted.

He explains how to use telltale signs in the IC packaging to identify which chip plant produced them, and visible indications of a chip that has been de-soldered from a board and reconditioned.

But this month I present to you, Good Reader, something a bit different. This particular model was selected for its ability to play MIDI files from 3. The piano itself still worked, but now required a human to do the playing. Anyone involved in the console wars at that time certainly remembers the classic, unique sound that those video game systems were able to produce, so [Aidan] built a device using a sound chip from a Genesis to play any piece of music from any game.

The second iteration of that project, though, is able to use those same sound files as a MIDI synthesizer. The interesting aspect of these chips is how they use registers to change the audio output. He built this entire thing from the ground up. There are dozens — dozens! As far as the case goes, a few modifications allowed [thk] to use all of the existing buttons, and a quick-swap of the back-plate and screen gave him a better enclosure than one he could fabricate himself.

The OPL3 was responsible for a lot of the music you associate with vintage video games like Doom. However, the interface to the codec is isolated in the code, so it ought to be possible to port the design to other hardware without much trouble.

If you prefer to do your synthesis old school, you can probably get a bulk price on chips. Gone is the front fork, which while common in motorcycle and bicycle design, has some problems. Fore-aft flex is one — two thin tubes will never make for a rigid front end. Changing geometry is another issue. Since forks are angled forward, the front wheel moves up and to the rear as the shocks compress. Forkless designs may not have these issues, but they bring in a set of their own.The chip is possibly stereo.

Channel 3 mode is absent. The chip is possibly mono. Channel 3 has two special modes:.

In general, these are inferior, stripped-down versions of OPL2. TODO: Is there anything programmable? Vibrato and volume? Has additional capabilities over OPL2, such as 4 more waveforms, double the channels, and ability to use 4-op instruments. Up to six 4-op instruments can be created, and each take up 2 channels. Also, there's a separate mode where you can add drums similar to OPL2.

Many musicians program their own drums in trackers using the full FM mode. TODO: Find out how the drum mode sounds like. Seems quite limited. Contains a built-in sequencer. Boasts much improved FM over MA Appears to have full OPL3 feature set. Also contains a sequencer. For drum sounds, a single key note can be specified. Improved over MA Much improved sample playback.It is backwards compatible with the Yamaha YMto which it is very similar — in fact, it only adds 3 new waveforms.

YM, showing the die surface. The circuit has different write-only registers. It can produce 9 channels of sound, each made of two oscillators or 6 channels with 5 percussion instruments available. This odd way of producing waveforms give the YM a characteristic sound. Each wave generator has its own ADSR envelope generator. Its main method of synthesis is frequency modulation synthesisaccomplished via phase modulation of the phase of one channel's oscillators by the output of another.

The internal operation of the chip is completely digital.

Each FM-tone is generated by a digital oscillator using a form of direct digital synthesis. A quarter of the log-transformed sine waveform is stored as a sampled approximation in a word read-only memory ROM table. The rest of the sine-waveform is extrapolated via its property of symmetry.

Scaling the output of an oscillator to a wanted volume would normally be done by multiplication, but the YM avoids multiplications by operating on log-transformed signals, which reduces multiplications into computationally cheaper additions [2]. Another word ROM stores the exponential function as a lookup table, used to convert the logarithmic scale signal back to linear scale when required, as the final stage where the oscillator-outputs are summed together just prior to the DAC-output buswith the modulator waveform always delayed by one sample before the carrier waveform.

Retrieved 19 August In the real world, sound is all around us, moving freely in any direction. We are immersed in this natural, multi-dimensional sound experience as we go about our daily lives.

Simply put, DTS:X makes sound move around you like it would in real life - without requiring specific speakers or custom configurations. From the big screen to home theaters to the phone in your pocket, DTS:X makes sound real.

DTS:X is the next generation audio codec from DTS that leverages object-based audio to enable new audio experiences in immersion and interactivity. DTS:X places sound where it would occur naturally in space, creating the most lifelike, multi-dimensional audio experience ever. Be prepared — this improved immersion and heightened realism makes horror movies scarier, comedies more laugh-out-loud, and car chase scenes even more intense. We made sound move, so your speakers don't have to.

Because DTS:X doesn't require any specific speaker layout, you can arrange your home theatre system however you want. Your movie collection gets a new lease on life! Take your favorite Blu-ray, DVD or digital movie to new heights. You are in control of your listening experience. That hard-to-hear line in a movie can be improved at a touch — lift the dialogue out from the background sounds when you want clarity and experience a more personal entertainment experience.

YPAO optimises the listening environment and fundamental high quality audio design, taking full advantage of the detailed spatial localisation capability of DTS:X. YPAO analyses room acoustics and performs speaker angle measurements, then calibrates audio parameters to achieve the best sound at any of several listening positions. The height of the presence speakers is also measured, in order to create the best possible 3D sound field.
