Please see our guide to optimizing Windows for audio. Windows generally needs a few additional adjustments to ensure optimal performance for use with Live, and indeed any audio processing.

If in doubt, make sure that this work is carried out by a professional computer technician.

Uninstall all unnecessary programs to keep your computer as efficient as possible.ĭisclaimer: Ableton cannot be held responsible for any computer damage or loss of data arising from the above maintenance.

A minimum of 10% is a good rule of thumb.

Ensure that you have adequate free space on your computer.

We recommend to clean the computer's fans and vents once a year. This results in thermal throttling, as the systems resources are increasingly reduced the hotter the computer gets.

If fans and vents are full of dust or lint, they need to spin harder and longer to keep the computer cool.

In addition, your computer should be regularly serviced to ensure optimal performance: Check out our guide on which computer to buy.

#Audacity crackling noise when recording upgrade

Check to see if it's possible to upgrade any individual components in your computer (RAM, CPU, Hard Disk etc). For audio applications, the more powerful your computer, the better. However even these minimum requirements may not be enough to cope with the workload, depending on how you use Live. Our minimum system requirements article lists the absolute minimum specifications required for Live to function. Underperforming computers may not be able to handle audio processing efficiently and this will increase the likelihood of audio crackles and dropouts. To avoid disk overload take the steps listed in our dedicated article: Avoiding Disk Overload. This is more likely to occur if triggering multiple large audio files at once. In this case the Disk Overload (D symbol) indicator will flash. If the hard disk cannot read or write audio quickly enough, you may hear dropouts. Make sure to close all other programs and processes on your computer which might be using valuable CPU resources. To reduce the CPU load in Live take the steps listed here: Reducing the CPU load in Live. When the CPU load on your computer is too high, you'll probably hear gaps, clicks or other audio problems in Live.

Also check the computer's USB port to make sure it's free of dust and lint.

Connect directly to the computer and not via a hub.

Check the connections and replace the cables/adaptors if necessary.

If using an audio interface which is connected via USB, Firewire or Thunderbolt, these cables or adaptors can easily cause crackles and dropouts if they have become damaged or are improperly inserted.

If in doubt, test using the computer's built in soundcard instead.

Make sure that your audio interface is compatible with this protocol.

Your computer may have USB 3.0 ports installed.

If the interface has been discontinued then you'll need to consider upgrading it.

Older interfaces may not have drivers available for your current operating system.Make sure that the audio interface drivers and firmware are completely up to date.

#Audacity crackling noise when recording driver

Check our dedicated article on Driver Error Compensation. Reset Driver Error Compensationĭriver error compensation set to extreme amounts may cause audio issues.

Note: Many ASIO audio interfaces only allow the buffer size to be changed via their own control panels. If there is no native ASIO driver available for your interface, you can use ASIO4ALL.For best performance we recommend using ASIO rather than MME/Direct X as the driver type.Note: Larger buffer sizes will also increase the audio latency. Reduce the In/Out sample rate to 44100 samples.Find the sweet spot just above where the crackles and audio dropouts stop. However, if the buffer size is set too low, then crackles, static noise, pops or dropouts may occur. In computer based audio systems a certain amount of latency, known as audio buffering, is necessary to ensure that playback, recording and processing results in an error-free audio stream. Ensure that no plug-ins are running in demo mode.

#Audacity crackling noise when recording update

Update all plug-ins and Max for Live devices.

Update your audio interface drivers and firmware.

Note: You can find more information in our Learn Live 11: Computer Performance video tutorial to help reduce the CPU load.įirst, make sure that everything is up to date:

In this troubleshooting guide we'll cover the most common reasons for these audio issues and how to resolve them. If the CPU load is too high and audio can't be buffered within the chosen buffer rate, then crackles, dropouts (gaps in playback), or glitches may occur during playback.
