Sound Systems

Limited time only.  Any purchase of the ASPIRE sound unit includes Multi Engine sounds for free.
Downloads of the P-38, B-24, B-25 and C-47 will be avaiable from 2/24 to 3/10 for download.  When purchasing, let me know in that you are interested.  I will send instructions on 2/24 with how to download the sounds, and put them on your own MicroSD card.

What sets the ASPIRE apart from previous versions, and other sound systems?

As an avid flyer myself, I strive to create a product that faithfully reproduces a scale sound that matches the real thing as closely as I can. Attention to detail is key. All new from scratch hardware using quality components. Innovation. New sound creation methods to produce realistic sounds. Personal and professional service all round out what you get from MrRCSound.

What hardware changes are in store for the ASPIRE?

Size: Approx. 2" x 3.25" x 1"

Weight: Approx. 2.2oz.

Power Input: 3S to 10S LiPO

Amplifier: A more powerful amplifier is being used. It is rated at 5X the power of the V4.1 amplifier, but it is being utilized at 2X the power of the V4.1 amplifier. This leaves overhead so the amplifier is not taxed, as well as staying within the safety limit of the TT-25 transducers. Using more of the amplifier ability in the future may be possible if design changes are made to the transducers.

Processor: A much higher end processor is being used. This allows faster computations of the sound, better response time, more features, and future enhancement.

Dual Board Design: The board, is actually 2 boards that connect together, one on top of the other. The bottom board is the processing unit, containing all the components for input, and processing the sound. The upper board is the power and amplifier section. All the components are sandwiched between the boards, with nothing hanging out. This allows for greater protection of the components in the event of a crash, slicker looking design, and easier handling. In the event you need to separate the boards for proper fitment, it is easily done with an optional communications ribbon cable.

Sound Memory: The memory style has changed from a chip style to a Micro SD memory card. This allows for much greater space for larger sound files, and ease of use. The V4.1 memory was 8mb total for all 6 stock sounds. The ASPIRE sounds will be approximately 110mb per engine sound! This allows for much higher quality (16 bit 44K CD quality), longer engine loops, and overall better performance. 

Expansion: The ASPIRE has an expansion port for a future "combat module".

How does the functionality of the ASPIRE differ from previous versions or other units?

There are number of things that separate the ASPIRE from the pack. The sound creation method is completely new, and there are many new functions in store.

Random Start/Shutdown:
 Each engine sound will have multiple startups and shutdowns for that respective engine. Real engines always have some differences each time they start and shut down. Sometimes an extra cough, sputter, rev up, etc.. To attempt to recreate this the ASPIRE will randomly choose a startup and shutdown of the respective engine. Thus giving a semi unique experience each time you fly. Engine sounds can have up to 15 different startups and 10 different shutdowns for the ASPIRE to randomly choose from.

Random Chatter/Sounds: One of the optional AUX. channels on the ASPIRE will have the ability to randomly select sounds. Depending on the engine being used, these could be aircraft related sounds, ATC chatter, or Pilot chatter, such as "Enemy, 10 o'clock high!" Other Aux. channels will have things such as guns, bombs, etc.

Automatic Whistle Trigger: Many aircraft have distinct whistle sounds, such as the P-51 or F4-U. The ASPIRE has a built in accelerometer, which will detect a pull out of a dive or hard turn, and automatically trigger the proper whistle sound. No need to trigger it manually as on the V4.1.

New Sound Rendering:
 MrRCSound has developed a completely new method for creating the engine sounds. It is a complex method which involves cross fading, speed and pitch changing and spectral morphing. Both the engine idle and the high RPM are real recordings of the respective engine. The processing allows for a very realistic ramp up and down through the RPM range.

What will I hear with the ASPIRE?

Richness: The first thing that you will notice is a much richer and fuller tone. The sound the APIRE delivers has a much higher quality sound, you will notice that there is much more bass tones, that give a better overall representation of the real engine.

Volume: Because of the new amplifier, the volume on most sounds is greater. Some sounds may sound significantly louder than those on the V4.1. Others may sound about the same, or even a little lower. This is perception because the sounds tend to have more bass, and fullness. Bass sounds tend to travel further however.

Prop Noise: MrRCSound has intentionally chosen high RPM sounds with a lot of the actual prop noise. This gives a more realistic sound in flight. Like on a real aircraft, there is not much prop noise at idle. While throttling up through the RPM range you will being to hear increasing prop noise, just like you would hear with a real aircraft.

Real Sounds:
 You can be assured the idle and upper RPM of each respective engine is taken from the real thing. The in between RPM range is rendered in a way which replicates the real RPM changes, giving an overall great effect.
