Converting SDIR files to more universally useful .wav files

Some of you will use Apple’s extremely useful Impulse Response Utility to make IRs. What this process results in is a .SDIR file that works seamlessly with Apple’s Space Designer plugin, but nothing else. These .SDIR files are really just

Tutorial – layering

I’ve — very quickly — dashed off two demonstration videos that show an approach to layering. In these films, I’m basically talking and using Reaper at the same time, not always in perfect coordination, but it shows an approach to

MetaData – 3

OK, so metadata injection can’t be much fun for many of you, but it has its uses down the line, especially tracing origins of material and organising things quickly and being able sort and reorganise yourself and your libraries. What

Ambisonic workflows with Reaper

What follows are instructions on how to make use of Reaper and the very powerful Ambisonics tool Kit to help you to spatialize your sound. It does not advise on what might sound good in a spatial context, but gives

Tutorial 04 – Gathering Impulse Responses (Objects)

The following is a brief overview of how to record impulse responses from software, outboard gear and acoustic objects using REAPER and Room EQ Wizard. This is supplementary to my (Jack’s) portion of Wednesday’s tutorial. I highly recommend that you also

Tutorial 04 – Gathering Impulse Responses (Spaces)

Capturing Impulse Responses of Spaces For a comprehensive overview, please refer to the supplementary material. You’ll need: A laptop with an IR utility software installed An audio interface Microphones (preferably omni-directional condensers) Speaker/s (if you are using a sweep) Things to

This post contains some useful information. While I’m not interested in encouraging you to hack DVDs and make production companies suffer, we do need to find ways to extract parts of films pull their audio and perform analysis on them.

03 – region rendering and speeding up editing in Reaper

Editing audio in Reaper can be fun and very quick. There are numerous features that allow you to speed things up, render differently processed versions of the same sound, batch create WAV and MP3, surround, binaural and bformat versions of

Impulse Responses & Convolution

Adapted from lecture notes by Varun Nair What is convolution? Convolution is the process where each single sample of a sound is multiplied by every sample of another sound. It is different from the plain multiplication of two sounds where

Making Recording Logs: Quick Tip

The following information and xsl parsing file was made generously by Owen Green in 2015. Reproduced here with thanks as it really takes the headache out of generating your spreadsheet of audio data. From Owen: Making recording logs can be

The FFT and Exploring Spectra

So far in the course we have generally considered the sound data we deal with to be in the time domain, as a sequence of samples (or a varying voltage) in time. Sometimes, however, it can be useful to work with
