Spatial Audio/Dolby Atmos for Starter Plans

Symphonic clients on the Starter plan have the ability to request Spatial Audio be added to their tracks.

Note: If you are on a Partner Plan, please click here for instructions on how you can upload Spatial audio.

• The Spatial Audio file's duration needs to match the Stereo Audio file's duration to be accepted.
• Symphonic charges $24.99 per Spatial Audio track (order form below).
• When a track has a linked Spatial Audio file, a Spatial tag will appear on the Release page next to the track number.

Dolby Atmos audio file requirements

Note: Dolby Atmos audio files generated from stereo mixes are not allowed.

• Provide the Dolby Atmos file as a Broadcast Wave Format Audio Definition Model (BWF ADM) file.

• All tracks within a project must be at the same frame rate.

• Ensure the LFE Channel does not contain audio outside of 3-120Hz.

• All audio must be 24-bit linear pulse code modulation (LPCM) audio at 48kHz.

• You must conform and sync the Atmos files with the stereo reference files for the same project.

• The integrated loudness value should not exceed -18 LKFS measured as per ITU-R BS. 1770-4.

• True-peak level should not exceed -1 dB TP measured as per ITU-R BS. 1770-4.

• For albums where gapless playback is intended between tracks:

  • Each album track must be delivered as an individual BWF ADM file.

  • Each track boundary must be no more than half a frame (1,000 samples @ 48 kHz) earlier or later than the same track boundary in the corresponding stereo deliverable.

  • There must be no additional silence at the end of each track when compared to the same track from the corresponding stereo deliverable.

Spatial ISRC

Just like a normal stereo recording, the Spatial Audio recording needs its own ISRC. If you don't have one, Symphonic will automatically assign one.

DSP Support

Spatial Audio Pricing and Order Form

Symphonic charges $24.99 per unique Spatial Audio file. We determine this by the Spatial Audio's ISRC.

You can submit your request by using the following form:

Like Stereo Audio, if you want to reuse Spatial Audio on another release, please reach out to us and let us know so that we can use the same Spatial ISRC when building your releases. This will prevent multiple charges for using the same Spatial Audio across your catalog.
