What is a Digital Signal Processor?

Best DSP Car Audio

When it comes to audio equipment the digital signal processor is often referred to as a whole machine, but specifically, it is a special type of microprocessor. The genesis of this processor started in an unlikely of places, first coming about in 1976 in a Speak and Spell. Today when people talk about DSPs they are usually referring to an entire device that hooks up to audio equipment.   A digital signal processor is a device that hooks between the source of your music to the amplifier. The source is typically a radio, but can also be anything that plays audio – such as a smartphone, laptop, cassette player, and so forth. The signal that is shot from the source must pass through the DSP on its way to the amplifier. While the signal is passing through you are free to modify the signal in a way you see fit.

What sets this device apart from others similar to it is that a DSP combines the capabilities of crossovers, equalizers, and line output converters all into one machine. These machines come in plenty of different features – each of which gives the user the ability to customize their music listening experience.

What to look out for with DSP Car Audio?

Best DSP Car Audio: Reviews and Buying Guide

There are a wide variety of different features and characteristics you need to keep in mind when out on the market for a digital signal processor. All of them should have plenty of headroom to avoid any sound distortion, along with controls that are compatible with digital devices.

  • Time Alignment: Because sound waves propagate through the air relatively slow, there is a fraction of a second difference between the different speakers from the driver’s position. By delaying the sound coming out of the closest speaker, allows a realignment of the sound. This removes the subtle echo effect and greatly improves sound quality, allowing you to listen to the music how it was meant to be.
  • Crossovers: This filter removes the bad upper and lower ranges of music, which can cause distortion in the music and the physical shape of the subwoofers and tweeters. The best crossovers cover a range of 20 Hz to 20 kHz, as this is the normal hearing range. This feature can also be used to remove the spotlight effect, or beaming, from occurring with a speaker system.
  • Equalization: This is the part of the system that directly controls the different frequencies of the music or sound coming out of your source. The number of these bands can be in the single digits or as high as 30. Keep it noted that while a higher level of bands gives you more fine-tune control, it also requires a bit more manipulation on your part.
  • Real-time Analyzer: This audio device is often incorporated into DSPs. As the name suggests they give a real-time analysis of audio signal and spectrum. When manipulating the signal from the source, users are able to get a visual representation of the level of changes they are employing when modifying the equalization controls.
  • Bluetooth: While this may seem minor, having a Bluetooth compatible device can be extremely useful. Once you download the relevant software, you can then wirelessly connect your device. This allows you to control your DSP with a phone or other smart device.

DSP Installation Tips

Knowing how to properly install your DSP is integral in getting the most out of it. Before you start pulling out those wires to get everything connected, there are a few things you should keep in mind.

  • Replace your factory speakers first: Digital Sound Processors can make a big difference, but they are considered more of a piece of equipment for more advanced setups. The cheapest thing you can do to improve your sound quality is to replace those lower tier speakers with an aftermarket model.
  • Unhook the ground from the battery: When doing any electrical work in a vehicle you need to first make sure that the source of the power is removed first. Remove the cable clamp from the negative battery terminal to ensure you don’t get any shorts when wiring.
  • Make sure to have the right wiring: More insulation is not only better, but larger cables also ensure that you’re getting sufficient power to your DSP and other equipment. Make sure to keep all wiring and cables away from any moving parts.
  • Every radio is different: You’ll need to remove the radio to get your DSP hooked up and it’s best to check with the manufacturer’s instructions to do that. You will probably need a small pry bar and a screwdriver to get it out. When in doubt check the seams of the dashboard, these usually pop up and allow you to get the radio out.
  • Keep track of those wires: This is especially pertinent if you are doing a full audio system install. Using some duct tape and a sharpie, mark each wire as you take them out and set them aside.
  • The DSP should be positioned away from any rattling: While most high-quality Digital Signal Processors have good headroom to prevent this, it’s always good practice to keep it away from any part of your car that might shake. A DSP that is rattling can produce inferior sound quality.

Final Thoughts
