  let {spec} = chunk.source!;
  let {dataType} = spec;
  let numElements = prod3(chunk.chunkDataSize!);
  let bytesPerElement = DATA_TYPE_BYTES[dataType];
  let expectedBytes = numElements * bytesPerElement * spec.numChannels;
  if (expectedBytes !== response.byteLength) {
    throw new Error(
        `Raw-format chunk is ${response.byteLength} bytes, but ${numElements} * ${bytesPerElement} = ${expectedBytes} bytes are expected.`);
  }
