The OpenAI Realtime Audio Delta Merger is an essential utility for developers working with the OpenAI Realtime API. When using WebSockets, audio streams are often fragmented into multiple discrete message events known as deltas. Network disruptions or intermediary agents can cause these chunks to be dropped or duplicated, leading to audible pops and broken synthesis. This MCP server provides a deterministic way to reassemble these fragments using merge_audio_deltas to concatenate base64 strings in their exact original sequence. You can also use check_sequence_integrity to audit the stream for gaps or duplicates and validate_base64_structure to ensure the resulting payload is structurally sound and safe for browser buffers.

3 tools expose this connector's capabilities to your AI agent.

validate_base64_structure

Represents the structural health of the reconstructed payload

check_sequence_integrity

Analyzes the input stream to detect if any audio chunks were lost or duplicated

merge_audio_deltas

Returns total chunks merged and estimated byte size. Merges multiple audio delta chunks into a single base64 string

I have an array of OpenAI Realtime events with audio deltas. How can I merge them into one playable string?

You can use the `merge_audio_deltas` tool by passing your events array as the `eventsArray` parameter. The tool will return the complete, concatenated base64 audio string.

Check if my recent WebSocket stream had any missing audio segments.

Run the `check_sequence_integrity` tool with your array of events. It will report the `gapCount` and `duplicateCount` found in the stream.

Verify if this reconstructed base64 string is valid for use in a browser buffer.

Use the `validate_base64_structure` tool with your merged string. It will return whether the payload is valid base64 and if it is safe for standard memory buffers.

It uses the `merge_audio_deltas` tool to iterate through your array of events and concatenate the base64 payloads in their exact sequential order, ensuring no audio loss occurs during reconstruction.
