Adjusting latency by changing the buffer size

“Latency” refers to the amount of time it takes for audio to get into and out of the computer. In the best of all possible worlds, there would be no such thing as latency—we would hear audio the moment it was created. However, computers have limited processing power, and they can “choke”—cutting off recording or crashing programs—if they are asked to handle too much data all at once.

To minimize this risk, audio can be stored in a buffer for a certain amount of time. This buffering helps smooth out the stream of data that the computer needs to handle. In the end, all of the audio is sorted out and played correctly, but with a delay.

Here are the basic considerations to consider when adjusting buffer sizes:

Lower buffer size = less latency but higher risk of audio problems

Higher buffer size = more latency but lower risk of audio problems

Very high buffer size = possible system instability

For most systems, there is a “sweet spot” where latency is not too high and system performance is good. Experiment with raising or lowering buffer sizes to hit this sweet spot.

As you begin adding plug-in EQ, compression, and so forth to your project, your computer will need to work harder. If you start to hear clicks, pops and other glitches in your audio, consider increasing your buffer size at this time.

As a final note, one tremendous benefit that the MultiMix FireWire offers is that you can monitor through it without latency at all. Simply press down the MIX TO CTRL ROOM button, and you can hear what you’re recording without havig to worry about your computer’s settings.

Adjusting the sample rate

You can change the sample rate that the MultiMix uses in this area.

Some audio programs require that you change the sample rate under their Project Setup or similar menus as well. For instance, in Cubase, be sure that the sample rate selected here matches the settings under the “Project” “Project Setup…” menu.

Many people use two latency settings—a lower one when recording tracks and a higher one when mixing.

The Alesis 12 FireWire and 16 FireWire mixers are innovative audio solutions designed for musicians, podcasters, and audio engineers looking to integrate seamless digital recording capabilities into their workflow. These mixers are equipped with FireWire technology, allowing for high-speed data transfer to computers, which is essential for real-time audio production and recording.

One of the standout features of the Alesis 12 FireWire mixer is its 12-channel configuration, allowing users to connect multiple audio sources, including microphones, instruments, and other audio devices. Each channel is equipped with a 3-band EQ, gain control, pan, and a selectable effect send, providing flexibility for sound shaping. The 16 FireWire model expands upon this, offering 16 channels to accommodate even larger setups for more complex audio routing and mixing scenarios.

Both models feature built-in FireWire interfaces that enable direct recording to a computer without the need for external converters. This integration simplifies the recording process and makes it easier for users to capture high-quality audio in a digital environment. The FireWire connection provides low latency, ensuring that performers can monitor their sound in real-time without noticeable delay.

In terms of build quality, the Alesis mixers are constructed with durability in mind. They feature robust controls, a solid chassis, and a user-friendly layout. This practicality makes them suitable for both studio and live environments, where reliability and ease of use are crucial.

In addition to the essential mixing capabilities, both models support various effects through their built-in processing. The 12 and 16 FireWire mixers come with several onboard effects such as reverb and delay, allowing users to enhance their audio without needing additional outboard gear.

Furthermore, these mixers support phantom power, enabling the use of condenser microphones that require additional power to operate. This feature is particularly advantageous for recording studios and live sound applications.

Overall, the Alesis 12 and 16 FireWire mixers are powerful tools that cater to the needs of modern audio professionals. Their integration of FireWire technology, extensive channel options, built-in effects processing, and user-friendly design make them an excellent choice for anyone looking to elevate their audio production capabilities. Whether you are working in a studio or performing live, these mixers deliver the quality and versatility needed to achieve outstanding sound.
