This is the first in an occasional series of podcasts devoted to some of my Hi-Fi heroes. This podcast is dedicated to Peter Walker, founder of QUAD. These days, QUAD is owned by the International Audio Group and many of its products form part of the current fashion for retro products.

However, during the first fifty years of its life, under the ownership of Peter Walker it was arguably the most innovative of British HiFi companies.

Peter Walker was a keen musician as well as engineer, and he favoured classical music, so we have chosen Handel’s Water Music to accompany this podcast, performed by The Jean-Francois Paillard Chamber Orchestra, in a recording from 1961, available from the Internet Archive under a Usage Attribution-NonCommercial-No Derivative Works 3.0 Creative Commons Licence.

This is the second part of the Hi-Fi Hobbyist Podcast on AI and Music. In this part we present the second side of the virtual album “Journeys”. Side 2 is made up of songs based upon real-life journeys undertaken by ancestors of the HiFi Hobbyist, or other people known to him. These journeys were often undertaken willingly in search of new opportunities and generally have positive outcomes. The music reflects the more positive stories on side 2 of the virtual vinyl album.

Following the music, there is a discussion of the issues around AI and music to conclude the podcast.

If you enjoy the music, please access the full release with lyrics and images at the main Hi-Fi hobbyist website

This week’s podcast is in two parts. It is a departure from the usual pattern, looking at the use of AI in the generation of music. There are legal and ethical issues, especially in the area of creativity and intellectual property, and we shall return to these at the end of Part 2 of the Podcast. This podcast is built around Journeys, a music and AI project developed by the Hi-Fi Hobbyist., featured in full on the main website at Hi-Fi Hobbyist dot net, as a virtual vinyl album with two sides, a cover and an album booklet with lyrics and further images. Within the “Journeys” project, the Hi-Fi Hobbyist acts as human creator, sets creative direction and has overall control, and views the use of AI as an instrument to achieve the desired outcomes in words, music, and images. The song lyrics are based upon ideas researched from historical and personal sources by the human creator. He maps out the narratives, then turns them into lyrics that fit the structure and meter, with the help of AI. The music is generated by the Mureka AI tool in response to detailed instructions provided by the human creator. Typically, Mureka generates four options, and then human creator then selects the most suitable version. Part 1 of the podcast presents Side 1 of the virtual vinyl album. Side 1 is made up of a series of songs about journeys based upon the historical events of the Highland clearances. It contrasts the journeys through life of those clearing and those being cleared. The music is in a Celtic style and draws upon the message and musical style of 7:84 Theatre Company's iconic The Cheviot, The Stag and the Black, Black Oil. Each song is linked to a historical event from the Scottish Highlands in the 19th century, although some artistic licence is employed.
