The acquisition, processing, and inspection of audio data plays a central role in the everyday practice of acousticians. However, these steps are commonly distributed among different and often closed software packages making it difficult to document this work. AKtools includes Matlab methods for audio playback and recording, as well as a versatile plotting tool for inspection of single/multichannel data acquired on spherical, and arbitrary spatial sampling grids. Functional blocks cover test signal generation (e.g., pulses, noise, and sweeps), spectral deconvolution, transfer function inversion using frequency dependent regularization, spherical harmonics transform and interpolation among others. Well documented demo scripts show the exemplary use of the main parts, with more detailed information in the description of each method. To foster reproducible research, AKtools is available under the open software European Union Public Licence (EUPL) allowing everyone to use, change, and redistribute it for any purpose: www.ak.tu-berlin.de/aktools.
