The setup for a listening test from the experiments folder according to the Processing Plan (IVAS-7) and Test Plan (IVAS-8) consists of two steps:
item generation and item processing. The two steps can be applied independent of each other.
For the two tests P800-1 and P800-2 (Stereo) the input audio files have to be low-pass filtered to 16kHz. This step is not necesary for all other tests.
This section describes step by step how to set up a listening test according to the Processing Plan (IVAS-7) and Test Plan (IVAS-8).
In the following sections the only purpose of the curly brackets is to mark the variables that thave to be replaced with the actual values.
## P800
The setup for a P800 test from the experiments folder consists of two steps:
item generation and item processing. The two steps can be applied independent of each other.
For the two tests P800-1 and P800-2 (Stereo) the input audio files have to be low-pass filtered to 16kHz. This step is not necesary for all other tests.
### LP filtering for P800-1 and P800-2
To low-pass filter the input signals run `python other/lp16k.py {input_folder} {output_folder}` from the root folder of the repository.

## MUSHRA
The set up for the MUSHRA test only consists of the item processing.
### Item processing
To process a BS1534-{X}{x} (X = 1, 2, ...7, x = a, b) listening test, the input files have to be placed in the folder 'experiments/selection/BS1534-{X}{x}/proc_input_{l}' and the command
`python generate_test.py BS1534-{X}{x},{l}` has to be run from the root of the repository. 'l' stands for the listening lab designator: a (Force Technology), b (HEAD acoustics), c (MQ University), d (Mesaqin.com).
The output can then be found in 'experiments7selection/BS1534-{X}{x}/proc_output_{l}'
