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.

这部份我们会分为小组作录音实践。 每组大约90分钟。

录音实践主要是将理论部份强化。例如录音不同元位和取样的聆听比较 / 咪高峰技术 / 混音 / 录音调整。学员可以取回录音的母带作往后比较。 本课程旨在增加音响爱好者的基本知识和了解一个录音的基本过程, 希望加强大家对音响及录音的兴趣。
