"Let's fiddle with the parameters"

After 10 minutes of repeating what seemed like a spell of some sort, Hiromi and his associate placed the receiver with an expression that they had sensed something. At that moment, the eyes of everyone in the room who had been waiting breathlessly had shifted to the lips of the two to hear what they had to say.

Let's fiddle with the parameters. The words that came out from Hiromi and his associate　were calm and quiet, unlike the shouts they were making moments before. But there was a sense of confidence in their words. And the words felt like a ray of light shining through the darkness.

Although the details are omitted here due to the complexity, the procedure for supplementing the shortage of LSI processing capacity by combining the four technologies of echo canceling, PAD, mute and level diagram was taken.

I was deeply impressed with the accurate analysis and flexible imagination of Hiromi. It was a skill that was possessed only by those who had complete understanding of sound. Some may regard the measure for supplementing the LSI capacity as a deception; however this later became the foundation for the technical advancement of IP telephony toward wide-spread deployment.

In retrospect, many communication engineers visited this anechoic room, buried their heads in their hands and gave us negative comments or words that pressured us. And many times, our expectations had turned into betrayal.

I thought of the solution presented by Hiromi as a true technical integration. This meeting with Hiromi was a stroke of faith that lead to sharing of the same vision even later on.
