Recording made on 21st October 2012 with a Sony PCMM10 on a Hama minitripod, using the builtin microphones covered with a Rycote Mini Windjammer. I have used a graphic EQ profile in WavePad to compensate for the slight muffling of the sound caused by the Windjammer. On this day, with large surf coming in and crashing on the cliffs, I had a hike on the North Cornwall coast path from Portreath to Perranporth, hoping to get the odd recording of the quintessential sound of the powerful Atlantic surf crashing on the cliffs, with the various deep thuds and whoomphs including very low, 'earthquake' frequencies. However, on this walk, up to the cliff prominence on the SW side of Porthtowan, I had been disappointed, for I had heard almost nothing of those really deep sounds, and all the surf sounded most genteel and undramatic from my clifftop perspective. But then, to get out of the breeze to be comfortable for my lunch break, on that prominence I started just a little down a narrow and scarily exposed track that contours obliquely down the almost sheer cliff face to the beach in Lushington Cove; the track is used by anglers and surfers of a certain nonnervous disposition. I sat there on the edge of the track for my lunch, with cliff face immediately behind me, having set up the recorder nearby, just off the track, in a rather precarious position. http://www.broadhorizonnature.co.uk/exposedclifffacetrackporthtowan_20121112_02.jpg In this particular situation, the cliff face was acting as reflector and resonator for the very low frequencies from the sound of the breaking surf, so there was a constant extremely deep rumbling and gentle booming. I and the recorder were facing across the bay, so that the surf was breaking generally on the right, with the hiss of the defrothing sea pushed in by each of the breakers spreading out in the centre of this grandstand view over the bay. This recording is of 'straight' surf breaking on a beach, so it is not the primary type of sound that I was particularly seeking. However, I was quite disappointed in the recording of this, for I found that the very low frequencies were not reproduced at all as strongly as I heard them, despite my hifi speakers having a pretty good very low frequency response. I suspect that my having the recorder on the minitripod and thus close to vegetated ground may have been the primary cause of that deficiency. Anyway, with a bit of trial and error, I gave a considerable boosting of those frequencies in WavePad, and uploaded this recording as 168106. Since then I experimented further, and this version replaces that one, with a more effective shaping of the bass boost, and also a small additional treble lift (all guided by the frequency spectrum graph displayed in Voxendo's Span plugin), which adds considerably to the detail and sense of spaciousness. The recording now comes much nearer to what I actually heard, although even now I think the very low 'earthquake' frequencies in the recording are not as strong as I originally heard but to boost them more in this recording would result in too much clipping or an overall reduced volume, which I did not want. Please note that only very good speakers / headphones with a very extended bass response will do this recording real justice. Also, it may sound unpleasantly boomy on speakers that have any sort of boominess (like my computer speakers). Please also note that the volume level of this recording has been carefully adjusted for listening purposes, and ALL my recordings so far are meant to be listened to with a volume setting that would give a realistic level for playback of CLASSICAL music (a large but not exceptional symphony orchestra). If you have the right volume setting, you should not need to change that setting from one recording of mine to another.(Later note: This recording with better sound than here is on one of my commercial CDs, and can be found in my eStore.)

描述:Recording made on 21st October 2012 with a Sony PCMM10 on a Hama minitripod, using the builtin microphones. http://www.broadhorizonnature.co.uk/shagrockperranporth500x375.jpg This photo of Shag Rock was taken while this recording was in progress.N.B. The sea and Shag Rock are bigger and further below than they look, because this is a longfocus shot. This recording was made on the very steep and rather precarious grassy slope below the rather exposed coast path a bit southwest of Perranporth, Cornwall, UK, which contours the main cliff slope from near Cligga Head to Droskyn Point, at which latter point you are in Perranporth proper. I had walked on the coast path from Portreath, and had been looking forward to this spot because on certain previous walks I had heard the surf really thundering here. Actually on this occasion, the sound was a bit too chaotic for me to think of it quite as 'thundering', but there was a lot of very deep booming and rumbling, with periodic heavy thuds, as the surf had vigorous and indeed dramatic arguments with the cliffs here that were in its way. I placed the recorder on a very low drystone wall running down the slope, with top completely covered with vegetation, and the minor headland with Shag Rock connected to its tip was ahead and somewhat to the right. This grassy slope ends just a little further below, in sheer and indeed more or less undercut cliff, so that the big waves make big rumbles and thumps as they hit the cliff (invisible to me on the steep slope above). However, that is not all that is happening, because quite large rebound waves keep interacting with new incoming ones, with the result that we hear sudden almost eruptive disturbances of the incoming waves. I'd wanted to make a full halfhour recording of this, but it was getting towards sundown and I was concerned that my return hitchhike from Perranporth to Exeter be not much delayed, so I intended to record for only ten minutes. However, as the sound was so thrilling there, I compromised by extending that to 16 minutes (though still rather regretting it not being a full half hour, and regretting so still more once listening to the recording back at home). Roughly halfway through the recording a light aeroplane passes over, which seemed annoying at the time, but actually in the recording it does give a little sense of perspective and so serves a reasonably positive function. Possibly because the recorder was very close to a vegetated surface, I found that the recording did not reproduce the very low frequencies at all strongly, and so, guided by the frequency spectrum graph in Voxengo's Span plugin, I used a straightline graphic EQ in WavePad to give a fair boost to the low bass, and uploaded the recording as 168105. Since then I experimented further, and this version replaces that one, with a more effective shaping of the bass boost, and also a small additional treble lift, the total effect adding considerably to the power and detail and sense of spaciousness. The recording now comes much nearer to what I actually heard. (Later note: Following further recordings at this location, I now think I was mistaken about that, and the EQ was unnecessary apart from that to correct for the Rycote Mini Windjammer, and thus I now view this recording as it now stands as significantly overtrebly because the recorder was not that close to the sea, and the amended bass, while sounding nice, has not really got the thundering 'welly' that has come out so well in my subsequent recordings there.) Please note that only very good speakers / headphones with a very extended bass response will do this recording real justice. Also, it may sound unpleasantly boomy on speakers that have any sort of boominess (like my computer speakers). Please also note that the volume level of this recording has been carefully adjusted for listening purposes, and ALL my recordings so far are meant to be listened to with a volume setting that would give a realistic level for playback of CLASSICAL music (a large but not exceptional symphony orchestra).

描述:Recording made on 11th November 2012 with a Sony PCMM10 on a Hama minitripod, using the builtin microphones covered with a Rycote Mini Windjammer. I have used a graphic EQ profile in WavePad to compensate for the slight muffling of the sound caused by the Windjammer. http://www.broadhorizonnature.co.uk/shagrockperranporth500x375.jpg This photo of the Shag Rock headland was taken during my previous recording there.N.B. The sea and Shag Rock are bigger and further below than they look, because this is a longfocus shot. This recording was made on the very steep and rather precarious grassy slope below the rather exposed coast path a bit southwest of Perranporth, Cornwall, which contours the main cliff slope from near Cligga Head to Droskyn Point, at which latter point you are in Perranporth proper. It was made at exactly the same spot as http://www.freesound.org/people/Philip20Goddard/sounds/168716/, with the recorder pointing in the same direction. As in that recording, I placed the recorder on a very low drystone wall running down the slope, whose top was covered with vegetation, and the minor headland with Shag Rock connected at the headland's tip was ahead and somewhat to the right. This grassy slope ends just a little further below, in sheer and indeed more or less undercut cliff, so that the big waves are in a state of pandemonium as they hit the cliff (invisible to me on the steep slope above). However, the state of the sea is quite different from when I made that previous recording here. Then the sea was relatively smooth apart from a big Atlantic swell, which was tending to start breaking before meeting the cliffs. This time the swell itself was probably not quite so large, BUT the sea as a whole was much rougher, and the tide was higher, so that none of the waves were breaking before meeting the cliffs, apart from the odd transient local eruptive 'breakings' where a rebound wave interacted with an incoming one. One thing that mystified me was the absence of obvious deep booms and thumps from the undercut cliff immediately below me in this position because (a) they were quite a feature in the previous recording here and (b) before I arrived at this spot this time I had looked across the line of cliffs and had seen a real continuous mayhem occurring just there, with repeated violent eruptions of spray as the waves hit the cliff, and with distinct 'whoomphs' clearly audible from something like half a mile away (i.e. in addition to those coming from the Shag Rock ructions) but as it was undercut I wouldn't be able to see any of that once at that spot, but at least I should have been hearing those 'whoomphs', which, as I say, seemed to be lacking this time. However, the sea made up for that by giving a whole succesion of dramatic eruptions of spray, with heavy 'whoomphs', as it kept hitting Shag Rock and the attached cliff of that little headland. The plumes of spray regularly shot up to or higher than the top of the cliff there. Also, some of the 'whoomphs' are strangely extended. Each of those was accompanied by a violent jet of spray shooting up at a 45 degree angle back over the sea. I guess there might actually be a blowhole there responsible for that. It was a bit bold of me to be making this recording at all, for, at 4.30 in the afternoon in early to midNovember, the light was already fading, and by 5.0 the dusk would really be deepening (requiring care on the exposed and rather stony and uneven track) and, once I'd got to Perranporth I still would have to hitchhike (in the dark) back to Exeter. I cut out about 45 seconds of the recording, at about 2 minutes in, because of a loudly conversational couple of walkers passing by on the track above. I would not mind the odd quiet human noises, but this was too obtrusive. This recording actually has continuous very gentle wind noise in the microphones but most of the time it is impossible to tell how much of the gentle booming and rumbling is from the sea on the cliffs and how much from the wind. However, the frequent discrete heavy booms and rumbles are at least almost all not wind gusts but the sea yet again hitting the cliffs. Please note that only very good speakers / headphones with a very extended bass response will do this recording real justice. Also, it may sound unpleasantly boomy on speakers that have any sort of boominess (like my computer speakers). Please also note that the volume level of this recording has been carefully adjusted for listening purposes, and ALL my recordings so far are meant to be listened to with a volume setting that would give a realistic level for playback of CLASSICAL music (a large but not exceptional symphony orchestra).
