Audio Formats and Delivery Standards
Understanding the technical requirements for audio delivery ensures that your creative vision is preserved from the recording booth to the final listener. This guide outlines the industry standards we employ at Razuwanuscapital to maintain sonic integrity.
The Importance of High-Resolution Source Files
When preparing files for mixing and mastering, the quality of the source material is paramount. In the professional audio landscape of Brisbane, we encounter a variety of home-recorded stems and studio takes. The golden rule is to always provide the highest resolution available. This prevents "digital artifacts" and ensures that the engineer has enough headroom to apply EQ and compression without introducing audible noise.
Working with high-resolution files allows for better manipulation of frequencies. For instance, a 96kHz file contains more data than a 44.1kHz file, which can be critical when performing time-stretching or pitch-shifting during the production phase.
Sample Rates and Bit Depth Explained
Sample rate refers to how many times per second the audio is sampled. While 44.1kHz is the standard for CDs, professional studio work often happens at 48kHz, 88.2kHz, or 96kHz. Bit depth, on the other hand, determines the dynamic range. 24-bit audio is the industry standard for recording and mixing, offering a significantly lower noise floor than 16-bit audio.
At Razuwanuscapital, we recommend delivering your stems in 24-bit WAV format. If you are recording at home before bringing your project to our Mixing and Mastering service, ensure your project settings are consistent across all tracks to avoid sync issues.
WAV vs. AIFF vs. MP3
For professional delivery, lossless formats are non-negotiable. WAV (Waveform Audio File Format) and AIFF (Audio Interchange File Format) are both uncompressed and preserve every bit of data recorded. While they are virtually identical in quality, WAV is the most universally accepted format across all Digital Audio Workstations (DAWs).
MP3s and other lossy formats should never be used for delivery. These formats discard "unnecessary" audio data to reduce file size, which results in a loss of high-frequency detail and a collapsed stereo image. Once a file is exported as an MP3, that data is gone forever and cannot be recovered during the mastering process.
Standard Delivery Checklist
To streamline the workflow and avoid delays, we suggest following this checklist when exporting your project for delivery:
| Requirement | Standard | Reason |
|---|---|---|
| File Format | WAV (Lossless) | Preserves full frequency spectrum |
| Bit Depth | 24-bit or 32-bit float | Maximises dynamic range |
| Sample Rate | 44.1kHz to 96kHz | Matches project session settings |
| Headroom | -6dB to -3dB Peak | Prevents clipping during processing |
| Processing | Dry (No Limiter) | Allows engineer to control dynamics |
Organising Your Stems
A well-organised session is a fast session. When sending files to our Brisbane studio, please name your tracks clearly. Instead of "Audio_01" or "Track_5", use descriptive names such as "Lead_Vocal_Main", "Kick_Drum", or "Bass_Synth_L". This allows our engineers to quickly identify elements and apply the correct processing without needing to ask for a tracklist.
If you have multiple takes of the same part, please provide only the selected "best" takes unless you specifically want the engineer to perform a comping process. This reduces the volume of data and focuses the creative effort on the final mix.
Delivery Methods and Storage
Given the size of high-resolution audio files, email is rarely a viable option. We recommend using secure cloud storage services. When uploading, ensure that the folder structure is intuitive and that all files are contained within a single archive or folder.
For those based in the Brisbane City area, you can also provide files via a physical drive during your session. We maintain a strict archive policy, storing your session files for 12 months to ensure you have a backup of the professional masters produced at our facility.
Local Considerations for Australian Artists
In the Australian music market, delivery standards often vary depending on the target platform. Whether you are preparing a release for Triple J or uploading to global streaming platforms like Spotify and Apple Music, the final master must meet specific LUFS (Loudness Units relative to Full Scale) targets. Our mastering process ensures your track is competitive in loudness while maintaining the punch and clarity expected by modern listeners in QLD and beyond.
Final Steps for Your Project
Once you have organised your files according to these standards, you are ready to move forward. If you are still in the recording phase, we highly recommend reading our guide on how to prepare for your vocal session to ensure the raw captures are of the highest possible quality.
