Section Two: Practical & Demo

We are very lucky that my personal friend and upcoming acoustic band A-dAY will join us as live performers. We will break all attendants into groups, so everyone is able to touch some knobs, and really be involved. We will go through the procedure of simple Miking & Mixing. We will demo some special post production equipment and further solidify theories that we discussed in theory section. We will record in different bit-rates, sample rates. Student can listen to each format and evaluate the theory behind it. At the end of this course, everyone will get a copy of these recorded materials in native high resolution.

這部份我們會分為小組作錄音實踐。 每組大約90分鐘。

錄音實踐主要是將理論部份強化。例如錄音不同元位和取樣的聆聽比較 / 咪高峰技術 / 混音 / 錄音調整。學員可以取回錄音的母帶作往後比較。 本課程旨在增加音響愛好者的基本知識和了解一個錄音的基本過程, 希望加強大家對音響及錄音的興趣。
