WEBVTT NOTE Transcript 2024-03-12 from FLAC by https://elvery.net/prototypes/transcribe/ on my MacBook Air M1 on maximum quality setting. NOTE Body lightly edited. 00:00.000 --> 00:07.140 Hi, I'm Damon Hart-Davis, and welcome to Earth Notes podcast on all things eco and 00:07.140 --> 00:10.520 green and efficient at home. 00:10.520 --> 00:14.100 19th April 2020. 00:14.100 --> 00:20.140 This meta-cast is primarily driven by documenting some specs and workflow to be consistent in 00:20.140 --> 00:22.680 putting together future episodes. 00:22.680 --> 00:30.120 I'm interested in opinions on the 48kHz to 44.1kHz divide that I'm crossing to. 00:30.120 --> 00:36.020 I promised not to do too many meta-casts, blame them on coronavirus cabin fever. 00:36.020 --> 00:40.080 My dad, Adam, worked in broadcast TV. 00:40.080 --> 00:44.860 The difference between the vibrant images on studio monitors at work and the anemic 00:44.860 --> 00:48.680 images on TV at home was a shock. 00:48.680 --> 00:55.120 Now I can relatively easily achieve technical audio broadcast master gamut (EG BBC Radio 00:55.120 --> 01:02.480 at 16-bit linear PCM with 48kHz sampling) in the comfort of my own home. 01:02.480 --> 01:10.280 The 48kHz Alliance says that "all audio production and distribution should go 48kHz. 01:10.280 --> 01:14.860 It's not about the slight superior audible quality of 48kHz. 01:14.860 --> 01:18.240 It's about being compatible with the video world." 01:29.100 --> 01:37.640 My shiny new Blue Yeti mic supports 48kHz, i.e. 48ksps or kilo-samples per second. 01:37.640 --> 01:43.440 I can't hear any particular different sampling at the two speeds and I wouldn't expect to. 01:43.440 --> 01:50.200 Moving to 48ksps sampling will expand the FLAC master copy by a little under 10%, but 01:50.200 --> 01:56.000 the MP3 files are being limited by output bitrate anyway, so shouldn't see any significant 01:56.000 --> 01:57.000 change. 01:57.000 --> 02:02.320 There were reports a few years ago of some MP3 players not coping with anything other 02:02.320 --> 02:09.320 than 44.1KSPS, but there doesn't seem to be anything recent, so it's likely not a significant 02:09.320 --> 02:10.320 issue now. 02:10.320 --> 02:17.480 Thus I see no reason not to do most or all future episodes at 48ksps, and so I have set 02:17.480 --> 02:21.800 Audacity's default project rate to that as a start. 02:21.800 --> 02:27.400 It occurs to me that if I record an episode away from home, on the NBA's built-in mic, 02:27.400 --> 02:34.560 I could consider dropping a sample right back to 44.1KSPS to save a bit of space, given that 02:34.560 --> 02:37.920 the extra texture just isn't there to capture. 02:41.640 --> 02:46.200 In the episodes page I have a how-to for the key elements of the workflow to prepare and 02:46.200 --> 02:48.040 publish an episode. 02:48.040 --> 02:55.320 At a slightly less nitty-gritty level, should the podcast have standard bookends, i.e. intro 02:55.320 --> 03:02.600 and exit, outro or coda, words and even jingle or signature music, having canned intro and 03:02.600 --> 03:06.980 outro may make for a more consistent presentation. 03:06.980 --> 03:11.160 They may not actually save production time as something now has to be imported into the 03:11.160 --> 03:14.200 piece rather than just being said. 03:14.200 --> 03:18.840 This also risks making things feel a little less organic and a little more robotic and 03:18.840 --> 03:19.840 over-professionalised. 03:19.840 --> 03:26.320 Still, no harm in laying down a couple to try now. 03:26.320 --> 03:33.200 A version of the sign-off used since the podcast start, Blue Yeti Mic 48ksps. 03:33.200 --> 03:40.120 There's more on my Earth Notes Web Site at Earth.Org.UK. 03:40.120 --> 03:45.600 Until now each intro has had some slight variations, sometimes with a small joke embedded, Corona 03:45.600 --> 03:50.640 cast, Diary cast, Meta cast and the date. 03:50.640 --> 03:55.520 Maybe a completely standard intro which can be followed by a date would be good. 03:55.520 --> 04:01.280 Here's the new intro used on this episode, 48ksps and Blue Yeti. 04:01.280 --> 04:10.640 Hi, I'm Damon Hart-Davis, and welcome to Earth Notes podcast on all things eco and green and efficient 04:10.640 --> 04:13.560 at home. 04:13.560 --> 04:19.120 I expect to add new, better versions of these intros and outros and switch to them. 04:19.120 --> 04:24.120 I may also flip between a small set of them to give episodes a little more variety and 04:24.120 --> 04:27.820 to reduce repetition blindness. 04:27.820 --> 04:32.320 More material will be added to this episode's page after it goes live, such as new intros 04:32.320 --> 04:36.680 and outros and updated workflow. 04:36.680 --> 04:42.600 There's more on my Earth Notes Web site at Earth.Org.UK.
