What this means in practice is that any rests between notes in your playing will be genuinely silent, rather than full of annoying hiss. They work the same way you set a noise threshold volume, and any sound that is quieter than that volume level will be silenced. Many amp sims feature built in noise gate simulations of the hardware pedals. With a real amp you would use a noise gate pedal. This is no different from a real hardware amp, and the solution is the same – to use a noise gate. If you are playing through some heavy distorted sounds, maybe you’re a heavy metal guitar player, you are likely to get a lot of hiss coming from the amp especially in the rests between playing. I highly recommend reading it if you are taking your first steps into the world of amp sims after using real amps. It goes into detail about the differences between real amps and software amps, including the advantages and drawbacks of each. For that reason, I have a whole article comparing real guitar amps to amp sims. the delay between when you play a note on the guitar and when you hear it coming out of the amp sim.Īs a quick aside amp sims are great, but they are not for everybody. This should also help reduce latency i.e. Check that this is set to “ASIO” or similar, and not a more general driver type such as “Windows Audio” or “Direct Sound”. In your amp sim go to the audio settings, and there should be an option called something like “Audio Driver Type”. If when using your amp sim you are suffering from pops or clicks, drop-outs, stuttering or unpleasant digital distortion, this may be because you are not using a dedicated digital audio driver such as an ASIO one. When you bought your audio interface, you probably had the option to download such a driver from the manufacturer’s website, or install one from a disc, or one installed automatically when you connected your interface to your computer. For example, on Windows there are drivers called ASIO drivers, which are specifically designed for digital audio. Your audio interface or sound card will require such a driver to let your amp sim or other audio software access its capabilities.ĭrivers come in lots of different types, from generic to highly specialized. Pulse by Lancaster Audio 2 Use specialist digital audio driversĪ driver is a small piece of software in your computer that handles the communication between an application and some hardware.There are plenty of free IR loaders available. Amp Sim (Lepou HyBrit) without an IR Amp sim (Lepou HyBrit) with an IR This should give you the sound you expect from a guitar amp and speaker cabinet.Ĭompare the sound of the Lepou HyBrit amp sim with and without an IR yourself in these audio samples…. In your DAW or other plugin host, you should put the IR loader after the amp sim in your signal chain. Others such as the Lepou amps and Ignite Emissary require a separate IR loader plugin to be used alongside them, with an impulse response loaded into them. Basically, if there is somewhere in your amp sim that you can add or configure a speaker cabinet, then you don’t need a separate IR. Some amp sims such as BIAS FX, Amplitube, Guitar Rig, have IRs and cabinet emulation built into them. If you use an amp sim without cabinet emulation from an IR, you will get a thin, fizzy unpleasant sound. In guitar terms, this is usually your amp. These are just like in a real-world hardware physical amplifier, where you have the actual amplifier that amplifies your guitar signal, and a speaker cabinet housing the speaker that outputs the sound to your ears.Īn impulse response (or IR) is a sonic measurement of the sound of a speaker, room or microphone in relation to a sound source. They have an amplifier part, and an impulse response (IR) or cabinet emulation part. Guitar amp simulators basically have two parts to them, much like a real guitar amp.
