 This essay introduces possible models of on-site acoustic field recording and its particularities.
1. So what exactly is a field recording? While reading these lines, you are  probably sitting in a room. Private or public, alone or with people –  in any case a space limited by walls, with a ceiling and floor, with a  door and possibly windows. Let’s consider this space as a ‘field’ and  place microphones in it. We are making a field recording.
 The exploration of what constitutes a ‘field’, considered worthy of  being documented, began around 1890 with Jesse Walther Fletcher’s  research on the Hopi and Zuni of the American Southwest. Since then,  field recordings have become an essential component of the field  research carried out by ethnologists and ethnolinguists. The second  large sector of field recording is – parallel to the concept of  photography – phonography, which refers to the recording of natural  sounds. Unprocessed recordings of nature and the environment play an  important role in today’s natural sciences including newer disciplines  such as bioacoustics.
 In 1913, field recording found its official entry into artistic practice  through the essay ‘The Art of Noises’ by the Futurist Luigi Russolo.  Since the early 60s of the 20th century, field recording has gained in  influence as a means and medium for compositional work. Almost  simultaneously the processing of sounds and sound recordings was found  to move into the areas closer to the core of the arts system – mostly in  connection with experimental concepts dealing with the architecture of  space and time.
 With regards to pure, unaltered field recording, defining its boundaries  in relation to music, physics, documentary field work and the arts is a  matter of each individual listener. But what do you imagine a ‘field’ to be and how could it be outlined as  an abstract model? To demonstrate this, we will turn on the microphones  and the recorder. We could declare this/any/your room to be a model and  thus assume the field was square (ill. 1). 
 This assumption coincides with certain characteristics: To begin with, a  square is the most evident symbol for a ‘field’ as a part of a whole.  It has defined boundaries and angles which are calculable. It  illustrates a territory possessing measurements and dimensions. It is a  closed entity, at least in this particular, most elementary case. You  could make yourself comfortable in a corner and continue to think about  whether the acoustic field you happen to be in actually is a square. If  we now try to ‘listen closely’, a process takes place which can be  understood as ‘listening all around you’. The sense of hearing describes  a directed circular movement around our head. Angles and corners cannot  be perceived. Thus, let’s try using a circle as our next model… 
 ill.2 
 Symbolically, the circle stands for an ‘entirety’ or also for ‘the  world’. Interestingly enough, it remains unresolved whether we are  dealing with the illustration of an inner or an outer world. In any  case, the circular model and the square share the qualities of  calculability and closeness. But calculability is a characteristic which  does not apply to any audibly existing natural surroundings. And  besides, nothing real is separated by boundaries. The sounds of the  world that lie beyond visually defined borders are also heard. The  audible or recordable space has neither square angles nor segments; it  may possess ‘intersections’ (to the auditory fields of other persons),  but its margins remain blurred. This lacking demarcation is illustrated  by means of a variant.
Ill. 3
 On the one hand, closeness of the membrane is broken open, and on the  other hand, the circle is four-dimensionally shifted around itself.  Surface is transformed into space; and the time that is required to  evoke the space in this manner is also taken into account. The model  Field B/Variant could stand for a spherical space of time within which  acoustic phenomena can be perceived and/or recorded. This model could  also be considered as the abstraction of an entirety, of which neither  the beginning nor the end are recognizable – the world as a field. The  model of worlds that touch and are conjoined by membranes reminds us in a  highly intriguing way of a foam flake. This basically is quite a useful  sketch, though it is indeed so comprehensive that the question  inevitably arises, at which point the subject with his microphone should  be positioned. Another field could be determined within the maelstrom  of multiple penetration, namely that of the perceiving/recording person.  It is, however, most unlikely that the documentarist together with his  field would accept to be installed in a space located outside of the  material physique of the existing world and its acoustic emanations. 
 Although the dotted arrows in this illustration indicate an interaction  between world and person, this concept hardly serves as an appropriate  model for a field recording. Whether perception encompasses our world or  the world embraces our perception will remain a paradoxical question  which does not allow for adopting a fixed position. The ears are – far  more than the eyes – a place of interpenetration between the inner and  outer world, between the centre and periphery. In order to put an end to speculations on right angles, circular or  ball-shaped fields, I would suggest applying an organic model for field  recording: the amoeba. 
Ill. 5
 As a protozoon, the amoeba is classified among the simplest existing  lifeforms and thus is well-suited for an abstract model. Other  characteristic traits are mobility, mutability, reactivity, blurred  boundaries and permeability. Additionally, it includes the aspects of  time and space. Let’s assume that the acoustic field surrounding us at  any given time resembles an amoeba and the documentarist equals the cell  nucleus (regardless of the fact that there also exist amoebas with  several nuclei, which, however, isn’t necessarily contradictory to  reality). The acoustic field is equipped with pseudopods branching out  to various sides, all depending upon what our attention is directed to.  Whether it is the shot of a revolver from outside the window, or the  clanging of a glass in the kitchen, the field stretches out towards it  and tries to envelope the phenomenon, focuses on it and registers it.  Each time we move, the surrounding acoustic field moves with us. In this  context, the quality of mobility can be understood both actively – a  spatial change – and passively, implying a shift on the time axis.
 By looking into biological details, the comparison can be pursued  further yet: Under the microscope the amoeba appears as a  semi-transparent mutable form. To be distinguished are: the usually  blurred cell nucleus, the transparent ectoplasm aligning the inner  membrane and the endoplasm filling the body along with the organelles  required for the osmotic equilibrium and food digestion. There is no  fixed relation between the nucleus and the organelles; both change their  positions within the field. The indistinctness of the nucleus  corresponds to the vaguely circumscribed consciousness of the  documentarist, who, in order to ensure proper functioning of the field,  fulfils the tasks of equalising tensions (with the exterior world) and  processing information.
 The amoeba as a possible model of field recording assimilates the  aspects of locomotion, indistinctness, permeability, space, time and the  particular processes which occur during a recording. The typical  dichotomy of interior and exterior, of site and surrounding, does not  apply. The same thing happens when we are listening to a field  recording. There is, however, another phenomenon appearing in the field  which I should like to term the ‘auratic fake’. Thus, if you’ve followed me so far, holding your book, sitting in your  room with that real or imaginary microphone, I suggest that you switch  off this device. Let’s go to replay and listen to the recording. Our  field recording will probably not be too spectacular, consisting of  distant music, the murmuring of traffic or perhaps the sound of clothing  rubbing against a chair, a dog barking or heavy breathing.  Nevertheless: Unlike any other medium, field recording allows the listener to be at two places at the  same time. By listening to a field distant to us in terms of space or  time, while dwelling in the present- time field of our recording, a  doubling effect takes place which may cause confusing disturbances in  the flow of our perception. Where does the listening subject begin and  where does it end? Between the ears, in this room, in another space  beyond?
