Introduction
At elasticStage, we transfer your content onto media as faithfully as possible, preserving the sound of your uploaded files without making creative or unnecessary changes.
Because vinyl and CD are physical formats, there are technical considerations to be aware of before uploading your audio. This guide explains how to prepare your files correctly for both formats based on how our system works today.
How elasticStage Handles Your Audio
We do not provide a dedicated mastering service.
We preserve the loudness relationship between tracks.
We do not make creative adjustments to your sound.
We only make technical adjustments where required (for example, CD true peak protection).
This sets expectations clearly and protects you legally.
Accepted File Formats & Technical Specifications
Supported File Types
We accept:
WAV
MP3
Files must:
Be stereo
Be at least 10 seconds long
Sampling Rate & Bit Depth
For Vinyl
Our vinyl is manufactured using high-quality converters running at 96 kHz / 24-bit.
For best results, we recommend uploading at 96 kHz / 24-bit.
Other supported formats:
24-bit or 16-bit
44.1 kHz
48 kHz
88.2 kHz
96 kHz
Any other sampling rate or bit depth will be converted to 96/24.
For CD
CDs are produced according to the Red Book CD standard, which is:
PCM
16-bit
44.1 kHz
Any other format will be converted to this standard.
Preparing Audio for CD
True Peak Level (-0.7 dB Limit)
To ensure compatibility across CD players:
If your uploaded audio exceeds -0.7 dB True Peak,
We attenuate all tracks by the same amount
This preserves the loudness relationship between tracks
Why?
Some CD players:
Mute audio
Introduce clicks
Produce distortion
when true peak levels exceed this threshold.
Loudness Relationship Between Tracks
We maintain the relative loudness between all tracks.
If one track is quieter intentionally, it will remain quieter.
CD Text Metadata
We embed metadata as CD Text, but not all CD players support this feature.
Preparing Audio for Vinyl
Vinyl has physical characteristics not present in CD or streaming formats. These affect:
Loudness
Bass
Treble
Side layout
Playback compatibility
We do not apply artistic mastering decisions on your behalf.
Track Layout on elasticStage
Unlike traditional vinyl masters:
You must upload tracks as individual audio files
We automatically lay them out with visible spacing
We do not introduce additional silence
If tracks should play seamlessly into each other, they will.
If you want silence between tracks, add it to the end of the preceding track (as streaming platforms do).
Vinyl Side & Space Limitations
Vinyl has limited space per side.
There is a trade-off between:
Duration
Bass content
Loudness
Longer or bass-heavy content:
Takes up more space
May reduce playback level
Quieter or shorter content:
Takes up less space
We produce vinyl at a default maximum playback level, but this may decrease if more space is required.
We maintain the loudness relationship between tracks per side.
High Frequencies & Inner Groove Distortion
Toward the centre of a vinyl side:
Treble quality decreases
Distortion increases
Very loud high frequencies (such as strong sibilance or aggressive cymbals) may cause distortion.
Common practices include:
Placing louder, brighter songs at the beginning of a side
Placing quieter tracks toward the end
Applying a de-esser to reduce excessive high frequencies
These are artistic decisions that we do not make on your behalf.
Bass & Phase Considerations
Common vinyl preparation practices include:
Converting bass content to mono
Avoiding long periods of negative phase correlation
Avoiding sudden amplitude changes (clicks, pops, bad edits)
Filtering content outside the audible spectrum
We provide a correlation meter in the Tracks tab.
If the meter stays in the red (between 0 and -1) for extended periods at high levels, vinyl quality may degrade and the risk of skipping increases.
Short red readings at low levels (e.g. reverb tails) are normal.
Do I Need a Separate Vinyl Master?
Vinyl mastering is not mandatory.
Well-mastered content prepared for streaming or CD often works well.
However, vinyl mastering can improve sound quality.
We do not provide a dedicated vinyl mastering service.
Vinyl Playback & Skipping
Vinyl playback depends heavily on:
Turntable quality
Cartridge
Weight calibration
Anti-skate settings
Cheaper turntables (typically under $100) are more likely to skip, especially with:
Loud cuts
Strong stereo content
We aim to strike a balance between:
Signal-to-noise ratio
Playback compatibility
Our manufacturing method allows for lower noise levels, which helps reduce skipping on affordable turntables.
However, no vinyl is completely skip-proof, especially on very low-cost players.
If you experience skipping:
Check your turntable setup
Check other records
Inspect the stylus
Clean dust
Adding Silence Between Tracks
We do not automatically add silence.
To create silence:
Add the desired silence to the end of the preceding track
Use audio software (e.g. silence generator tools)
This follows the same principle used by streaming platforms.
Test Copies
We strongly recommend ordering a test copy before releasing your vinyl, especially if you are new to the format.
If adjustments are required:
Retire the release
Clone it
Upload revised audio
Final Audio Preparation Checklist
Before uploading your audio to elasticStage, make sure:
For All Formats
Files are WAV or MP3
Files are stereo
Files are longer than 10 seconds
There are no unintended clicks, pops or dropouts
Track order is correct
Any required silence has been added manually
For CD
True peak does not exceed -0.7 dB (if it does, we will lower all tracks equally)
You understand that CDs are produced to the Red Book 16-bit / 44.1kHz standard
For Vinyl
You are aware of vinyl’s physical limitations
Excessive stereo bass has been avoided
Long periods of negative phase correlation have been avoided
Very bright, sibilant tracks are not placed at the end of a side
You have reviewed the correlation meter
You understand that playback quality depends partly on turntable quality
Next Step: Uploading Your Tracks
Once your audio is prepared, you can upload your tracks individually.
