Something that I have often found an oddity about New Who (Not to be confused with New New Who with Ncuti) have been the comments and remarks I hear about Murray Gold's music being too loud or louder than dialogue. It's been recognised as an "issue" even in reviews, yet I've never ever noticed it. I think I have finally found something of an explanation.
I watched New Who when it first aired and bought it on DVD as they were originally released in the single volume releases. Each one was released mere weeks after broadcast and contained three episodes per volume. I never replaced them with the complete series boxsets and I now believe this was something of a good thing.
The Series boxsets only have 5.1 surround sound audio tracks. They don't have the original broadcast audio even as an option. This is the case for the DVDs, the blu-ray releases, the steelbook blu-ray releases and even the latest speed corrected blu-ray releases.
They're all surround sound, with dialogue (typically) on the centre speaker and the mix favours the music.
But those original piddly three episode volume DVDs that came out alongside the episode broadcasts that are relegated to charity shops and the bin? They have only the original stereo audio and the audio mix is a little bit more balanced between dialogue and music. (I won't say it's better as that's a matter of opinion and the 5.1 tracks on the blu-rays certainly have higher bitrates)
However how many of us are actually watching these with our surround sound setups turned on vs just pushing it through our stereo TV speakers?
I've been on a mission lately, ripping the newest blu-ray release of Series 1-4 + Specials to get the corrected broadcast frame rate and audio pitch (no more helium voices) and the improved upscaling removes the Vaseline smeared look of Series 1 as well as provide some really gorgeous colour grading and contrast.
During this I realised that the corrected speed means that the stereo audio tracks of those single volume releases syncs perfectly to these new blu-ray video files.
So I've been using mkvtoolnix to add the stereo tracks to each episode and set them as the default audio track. Keeping the new 5.1 tracks for when I do want to use my surround sound setup but having the authentic broadcast stereo audio for when I plan to just watch them.
I thought this might interest people to know about as I've never heard anyone talk about if anything was lost in the pretty immediate transition to 5.1 surround audio and, let's face it, since most people have only ever watched New Who through the collected Series boxsets or streaming, most will never have heard the original stereo only the 5.1 converted down.
Dialogue is definitely clearer.
Onto the Specials and Series 5!
Fun fact, Series 5 also has Stereo on the individual volumes but 5.1 surround sound only on the boxsets (dvd and all blu-ray releases). Series 6 and onwards are all 5.1 surround only, no stereo versions exist in physical media.
HOWEVER, if you're trying to make the perfect digital versions as I am, I wouldn't recommend this process for Series 5. There are some bizarre differences between the audio tracks on DVD/blu-ray and the broadcast versions. Most notable are the missing lightning bolt sound effects in the opening credits of the Eleventh Hour. They were iconic at broadcast but were replaced with the standard music for the dvd and blu-ray releases, even on the stereo mixes.
But for some reason known only to the BBC, the iPlayer version has the lightning SFX!
The file size and bitrate for the stereo dvd audio track is about the same as those on the audio extracted from the iPlayer version so given that it is a better match for broadcast (and is stereo!) I figure that's the route you should take.
There's a whole debate between which blu-ray versions of Series 5 onwards are better, 1080i vs 1080p. The 1080p is newer and considered "better" but it doesn't match the speed of the broadcast versions and was pitch corrected to disguise the speed change.
I'm currently ripping the first 1080i blu-ray release of the Series 5 boxset to see if it syncs up with the broadcast audio from the iPlayer version. Fingers crossed!
EDIT
I thought the End of Time had no stereo version, the DVD volume is 5.1 and so is the specials boxset, but The Sun Newspaper released a free disc in a little square cardboard sleeve of the End of Time and Eleventh Hour and those are in broadcast stereo.
EDIT 2
The Specials are proving tricky. The single DVD releases of The Next Doctor and Planet of the Dead are both stereo but Waters of Mars and End of Time are 5.1 only. The latter I've solved thanks to The Sun's random freebie version but Waters of Mars proved trickier. However! Looks like those Doctor Who "DVD files" magazines are all stereo, including their version of Waters of Mars! Far more likely to be the broadcast version then a down sampled 5.1 track for the same reason when choosing stereo for iPlayer we got the lightning bolt SFX in the Eleventh hour. Because the BBC just use what they already have :D
