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.

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. 

In a previous podcast, we looked at Chi-Fi, Chinese-manufactured Hi-Fi, which is gaining increasing recognition in the international Hi-Fi market. In this podcast, we will look in more detail at how this industry has developed from a low-cost manufacturing centre to an innovation and R&D hub, and how Chinese brands are now building products based on their own innovations that can match or outperform traditional rivals from the West. 

Last week's podcast looked at the issue of room acoustics and room treatment. This week, we hand over the topic to AI protagonists for a debate about whether specialist room treatments are required in a domestic setting, or whether simpler pragmatic adjustments to room decor with the potential addition of digital signal processing can suffice. As always, the purpose of deploying AI is to provide an alternative view of the issue. 

The accompanying music this week is from the Planet Suite by Gustav Holst, played by the USAF Heritage of America Band and supplied by musopen.org, and available in the public domain. 

I hope you enjoy the debate!

 Recent opinion pieces on the HiFi Hobbyist website have reported on differing views from online commentators on the importance of room acoustics and room treatments.

In this podcast, we will look in more detail at the underlying scientific theory and seek our own conclusions on the topic. 

This week's podcast is a generated discusison take a deeper look into how the recording quality of live albums improved over the 1970s. The discussion is not limited to the five albums I discussed last week, and the discussion has a more U.S-centric feel which may balance things for those who think my choices last week were too UK-biased. Once again, I have generated accompanying music to show how AI thinks live rock music from this period sounds .

For me, the 1970s were a golden age of the double live album. Of course, these were the days of vinyl, so we’re talking about four sides, giving a total playing time of up to about 90 minutes.

Speaking personally, this was how I got to know some of my favourite bands of this era. In this podcast, I will seek to identify my five favourite live albums from the period and discover how they were recorded.

What are your favourite live albums from the era? What memories do they evoke?

I hope you enjoy the podcast

This week’s podcast is the last in a cycle of four. Using the same sources as the Hi-Fi Hobbyist did last week, our AI protagonists discuss the significance of the key recordings of Beethoven’s 9 Symphonies. 

This week’s music accompanying the podcast are selections from an early recording of Arturo Toscanini conducting the BBC Symphony Orchestra in a performance of Beethoven’s Symphony No. 6 in F major, Opus 68, the ‘Pastorale' at the Queen's Hall, London in 1937, first released in 1943 and now in the public domain and available at Wikimedia Commons. Listen for the genuine surface noise of a 78 rpm shellac record faithfully reproduced on the digital transcription! 

This week’s podcast is the third of a four-week cycle. This week will review recordings of Beethoven’s nine symphonies from the last one hundred years. This will be followed next week by letting our AI protagonists discuss the most significant recordings of Beethoven’s symphonies.
