Create and share a MATLAB library that performs data augmentation algorithms for audio data. This study aims to help machine learning researchers to improve their models using the algorithms proposed by the authors.

The authors structured our library into methods to augment raw audio data and spectrograms. In the paper, the authors describe the structure of the library and give a brief explanation of how every function works. The authors then perform experiments to show that the library is effective.

The authors prove that the library is efficient using a competitive dataset. The authors try multiple data augmentation approaches proposed by them and show that they improve the performance.

A MATLAB library specifically designed for data augmentation was not available before. The authors are the first to provide an efficient and parallel implementation of a large number of algorithms.

THE great advantage the contemporary librarian enjoys is the opportunity of meeting his fellows at so many library assemblies. It might almost be wondered whether, in such opulence, the one great Conference in September is really necessary: a wonder that is immediately modified by the thought that no other meeting can give a representation of what the profession as a whole is doing or hoping to do; the many parts of the whole come together briefly then. It is the more necessary that the Conference makes this annual revelation, and does it manifestly. This is “much easier said than done”. Looking back on the almost complete disregard by the Press of the Folkestone meeting, in spite of our own statement that we had sought publicity for at least half a century in vain, we are compelled to think that renewed efforts should be made to attract the newspapers, radio and T.V. in the service of libraries. We are assuming that such notoriety is desirable, an assumption which some deny. If it is, our programmes must be ready sooner, advance matter of papers should be in the hands of editors before they are read, paragraphs for the B.B.C. and other public address organizations should be prepared and distributed even longer, before the newspapers get them. All this, however, must be based upon the proceedings themselves which, as we have affirmed often, should with a few inspirational exceptions be based upon the programme of service every type of library gives to the community.
