Ingemar Ohlson with Håkan Lindberg Swedish section, 29th May 2105
A busy spring for the Swedish section included cooperation with local trade association LLB. 3 seminars were held at the recent show covering electroacoustic reverberation techniques, digital audio encoding techniques and studio design.
AES member Håkan Lindberg provided the lecture for the May section meeting on the subject of microphones. The evening was split into two with the first part being an historical overview of microphone development during the last hundred years. Håkan's background in film sound provides him with a unique insight into the techniques and technology used in the movie and television industry. The talk covered everything from early optical recording techniques to modern condenser microphones. The second part of the evening provided a deeper examination of the technology inside the microphones we use.
Håkan's talk was interspersed with fascinating audio examples. One in particular was a recording made in the early 1900's which had been digitally extracted using modern algorithms from optical discs (glass discs coated with photographic emulsion). Other examples were orchestral recordings made with classic Neumann mics restored to their original 1930 condition and recorded to digital formats — which proved that microphone technology was highly advanced as early as the 1930s.
The meeting was well attended and participants pose questions and observations throughout the evening.
