Waves: Filter Out Unwanted Data

Overview

Filter out unwanted data by removing specific data points and/or ranges of data values. The filter operation utilizes the real-time expression comparison operators (!=, ==, <, <=, >, >=). Comparison operations can be chained together to apply multiple filters.

*Real-time expressions are available in the Personal and Pro tiers.

Syntax


A Single Filter
=[data stream] <operator> <value>

Multiple Filters
=[data stream] <operator1> <value1> <operator2> <value2> <operator3><value3>

Example



In the example above, the signal, pitch, has several spikes of greater than 100 that are dominating its view range. Those spikes can be filtered out to set the spark-line y-axis range to show the signal minus the large spikes by using the following expression:

=[pitch] < 100
