Five tips for reducing delays in recording

Delay can destroy the performance of the recording, but the delay can be completely avoided or reduced. Use the following five tips to find out how to minimize or even completely eliminate delays.

The audio buffer (Buffer) is a smaller, constantly active virtual space. This space is used by your computer to receive audio during audio reception. Then the audio is passed through the space to the software and then returned again so that you can hear the audio. In fact, this action takes only a very short timea few hundred milliseconds. But the ears of music performers are very sensitive to time, and even a delay of a few milliseconds may make the recording work difficult. Even if a quarter-second gap can make the playing midi note and the result of the hearing trouble the recording, this trouble is enough for you to drink a pot.

Setting a lower buffer size (256 samples or less) will effectively reduce latency - lower buffers will have lower latency. But this action also increases the CPU reading load on your computer, which can make the CPU need to process audio even faster. If the computer does not have the ability to keep up with the speed of processing, an error will eventually occur. If you have a powerful computer with a reliable sound card driver, adjusting the value to 128 or even 64 samples is a small case.

2. Change the buffer in different situations

This is easier to understand - smaller buffer sizes are equal to lower latency but higher CPU usage, larger buffers mean lower CPU usage and more latency. But in different occasions, the demand for the process of making music is also different. For example, when you are recording live, low delay is a must. But when you are mixing, the delay of the recording is almost irrelevant, and the larger CPU power is the king. Therefore, remember to adjust the size of your audio buffer to fit the actual work on hand.

3. Frozen track

Based on the previous tips, you may find yourself having to add more tracks in the production process later, and then the computer is already under heavy load and runs a very heavy project. If this is the case, use the audio tracker (DAW)'s Freeze Track feature to save the consumption of audio track resources and then switch to a lower buffer size for recording. After the recording is completed, the thawing track resumes buffering to a higher setting.

Some audio hardware interfaces, even some of the most cost-effective models, will have the option to listen directly to this option. This will send the signal to the software before it is sent to the software by playing your input (such as from a microphone or a guitar). beats earbuds Your headphones. This means that there is basically no delay. The disadvantage of this is that you can't hear the effects of recordings, such as reverb effects, unless your sound card comes with DSP processing effects, which can be adjusted directly in the sound card. In summary, direct monitoring is a very high-quality solution beats headphones cheap for many players and does not involve interference with buffer occupancy.

This is almost related to all software, but this is especially important for recording. There are many variations of music settings, and if you change your current operating system, audio workstation or other software, it may cause unforeseen problems. The problems that occur in those recordings are often (sometimes) caused by ancient drivers - behind the level of the driver software, causing problems with the dialogue between your hardware and your software. So keep updating your driver to avoid this problem as much as possible.
