The Quick Calculator plugin for Audacity is a versatile tool for performing a variety of calculations, from simple arithmetic to frequency conversion. It allows users to quickly and easily perform calculations related to dB, BPM, MIDI, Hz, tempo and length, degrees and radians, and Nyquist code. The plugin is designed to be user-friendly, allowing users to select from a drop-down menu the type of calculation they want to perform. Depending on the type of calculation, users may be prompted to enter one or more values. The plugin then performs the calculation and displays the result. For example, if the user selects "dB to Linear" from the drop-down menu, they will be prompted to enter a dB value and the plugin will then display the linear equivalent of that value. The Quick Calculator plugin is a great tool for quickly performing calculations related to audio engineering, music theory, and programming. It can be used to quickly calculate dB values, tempo changes, frequency conversions, and more. With its user-friendly interface and wide range of calculations, the Quick Calculator plugin is a must-have for any Audacity user.
To calculate the tempo change between two BPMs, open the Quick Calculator plugin in Audacity. In the "Type of Conversion" dropdown menu, select "Tempo Change as %". In the "Direction of Conversion" dropdown menu, select "Normal (forward)". In the "Enter data to evaluate" field, enter the two BPMs separated by a space. Then click the "Calculate" button. The plugin will then display the percentage change between the two BPMs. For example, if you enter "120 180" in the "Enter data to evaluate" field, the plugin will display "Tempo change from 120 bpm to 180 bpm is 50 %."
To find the frequency of a MIDI note, open Audacity and select the ‘Generate’ tab. From the dropdown menu, select ‘Quick Calculator…’. In the ‘Type of Conversion’ dropdown menu, select ‘MIDI to Hz’. In the ‘Enter data to evaluate’ field, enter the MIDI note number. Click ‘OK’ and the result of the conversion will be displayed in the ‘Output’ field.
To convert dB to Linear using the Quick Calculator plugin in Audacity, open the plugin window by selecting "Generate > Quick Calculator..." from the menu. In the plugin window, select "dB to Linear" from the "Type of Conversion" dropdown menu. Then enter the dB value you want to convert in the "Enter data to evaluate" field. Click the "Preview" button to generate the result. The result will be displayed in the "Output" field. The result will be a linear value that corresponds to the dB value you entered.
To calculate the length change between two durations, you will need to use the Nyquist Quick Calculator plugin in Audacity. To access the plugin, open Audacity and go to the "Generate" menu. Select "Quick Calculator..." from the list of options. In the Quick Calculator window, select "Length Change as %" from the "Type of Conversion" dropdown menu. Then enter the two durations in the "Enter data to evaluate" field. Make sure to separate the two durations with a space. The output in the "Result" field will be the length change between the two durations as a percentage.
Evaluating Nyquist Code with Quick Calculator allows you to easily convert a frequency (in Hz) to a period (in samples). To do this, select "Frequency (Hz) to Period (samples)" from the "Type of Conversion" dropdown menu. Then, enter the frequency (in Hz) you would like to convert in the "Enter data to evaluate" field and click the "Calculate" button. The output will be the period (in samples) at the current sample rate.
