Performance Aspects

Tracks and Effects

The faster your computer, the more tracks, effects, and EQs you are able to play. Exactly what constitutes a fast computer is almost a science in itself, but some hints are given below.

Short Response Times (Latency)

One aspect of performance is response time. The term “latency” refers to the buffering, that is, the temporary storing of small chunks of audio data during various steps of the recording and playback process on a computer. The larger those chunks, and the more there are, the higher the latency.

High latency is most irritating when playing VST instruments and when monitoring through the computer, that is, when listening to a live audio source via the Nuendo MixConsole and effects. However, very long latency times (several hundred milliseconds) can also affect other processes like mixing, for example, when the effect of a fader movement is heard only after a noticeable delay.

While Direct Monitoring and other techniques reduce the problems associated with very long latency times, a system that responds fast will always be more convenient to work with.

• Depending on your audio hardware, it may be possible to trim your latency times, usually by lowering the size and the number of buffers.

• For details, refer to the audio hardware documentation.

Audio Hardware and Driver

The hardware and its driver can have some effect on regular performance. A badly written driver can reduce the performance of your computer. But where the hardware driver design makes the most difference is with latency.

This is especially true when using Nuendo for Windows:

• Under Windows, ASIO drivers written specifically for the hardware are more efficient than the Generic Low Latency ASIO Driver and produce shorter latency times.

• Under macOS, audio hardware with properly written macOS (Core Audio) drivers can be very efficient and produce very low latency times.

However, there are additional features only available with ASIO drivers, such as the ASIO Positioning Protocol.
