Rode Merge - Rodecaster Pro Multitrack Processor

A shell script for processing and merging multitrack WAV recordings from the Rodecaster Pro podcast recorder into single-track time-corrected FLAC files.

Prerequisites

• ffmpeg with FLAC support must be installed on your system
• Rodecaster Pro multitrack WAV recordings (POD*.WAV files)

Installation

1. Download the rodesplit.sh script
2. Make it executable:

chmod +x rodesplit.sh

Usage

1. Place the script in the same directory as your Rodecaster Pro WAV files (POD*.WAV)
2. Run the script:

Basic usage (processes all 4 mic channels):

./rodesplit.sh

Process specific channels:

./rodesplit.sh host guest

Processes only the mic1 and mic2 channels and applies the filenames "host" and "guest"

Features

• Extracts individual microphone channels from multitrack recordings
• Converts audio to FLAC format for better compression
• Applies time correction to fix clock inaccuracy issues
• Automatically concatenates multiple recording segments
• Supports processing up to 4 microphone channels
• Cleans up temporary files after processing

Channel Layout Reference

The Rodecaster Pro uses the following channel layout:

1. Main Output - Left
2. Main Output - Right
3. Mic Channel 1
4. Mic Channel 2
5. Mic Channel 3
6. Mic Channel 4
7. USB Channel - Left
8. USB Channel - Right
9. Smartphone Channel - Left
10. Smartphone Channel - Right
11. Bluetooth Channel - Left
12. Bluetooth Channel - Right
13. Sound Pads Channel - Left
14. Sound Pads Channel - Right

Output

The script creates individual FLAC files for each processed microphone channel:

• mic1.flac
• mic2.flac
• mic3.flac
• mic4.flac

Notes

• The script assumes all POD*.WAV files in the directory are from the same recording session
• A maximum of 4 tracks (the microphone channels) can be processed at once
• Temporary files are automatically cleaned up after processing
