This research project aims at studying and finding a suitable method to implement audio bandwidth extension to bandlimited audio files. The idea is to reconstruct the missing high frequency spectrum in bandlimited audio/music using a couple of non-linear processes (rectification) along with some filtering techniques to reduce distortion.

Audio coding is a generic technology to IoT applications system. Audio bandwidth extension is a standard technique within contemporary audio codecs to efficiently code audio signals at low bitrates. In existing methods, high frequency signal is generated by a duplication of the corresponding low frequency and some parameters of high frequency.

Bandwidth extension has a long history in audio pro-cessing. While speech processing tools do not rely on side information, production-ready bandwidth extension tools of general audio signals rely on side information that has to be transmitted alongside the bitstream of the low frequency part, mostly because polyphonic music has a more complex and

Bandwidth extension - Wikipedia
https://en.wikipedia.org/wiki/Bandwidth_extension
Bandwidth extension of audio. Spectral band replication (SBR) is a new technique that has gained popularity as an “add-on” to popular perceptual audio codecs such as MP3 and the Advanced Audio Coding (AAC). New audio coders consisting of a marriage between SBR and the conventional audio coders have been formed, namely the MP3Pro and AAC+. In these …
