<p>AMMS-Net can make an audio clip, which had been recorded with a single microphone, provide a better and realistic hearing experience to users.</p>
<p>For example, there are people playing instruments and singing in the above video.</p>
<ul>
<li>The location of each person is
<ul>
<li>bass guitarist: rightmost</li>
<li>vocalist, playing piano: right</li>
<li>drummer: relatively left</li>
</ul>
</li>
</ul>
<p>We can make a better audio clip in terms of the <em>spatial audio</em> with AMSS-Net.</p>
<ul>
<li>For example,
<ul>
<li><strong>pan bass completely to the left sid</strong>e: left 100% and right 0% (the operation 1 in the table below)</li>
<li><strong>pan vocals to the right side</strong>: left 20% and right 80% (the operation 2 in the table below)</li>
</ul>
</li>
<li>Also we can <em>modify the timbre of specified instrument</em> to avoid interference of different sources.
<ul>
<li>by typing <strong>apply highpass to drums</strong> (the operation 3 in the table below)</li>
</ul>
</li>

<p>An audio clip may contain noises such as people shouting noise in the middle of a concert.</p>
<ul>
<li>For example, in the above youtube (from the movie Begin again),
<ul>
<li>a man shouts (starting from 0:08 in the original audio clip in the table below)</li>
<li>in the middle of a rooftop busking to ask them to stop playing</li>
</ul>
</li>
</ul>
<p>We can also observe <em>reflections of some sounds</em>, especially from the kick drums, which might annoy some listeners.</p>
<p>We perceive them more severe when we increase the volume of those instruments (the operation 1 in the table below)</p>
<p>Then, we can make a better audio clip to remove unwanted sounds or remove the <em>reverberation effect</em> with AMSS-Net as follows:</p>

<p>We are used to some dramatic introduction with musical effects such as <em>fade-in</em> or <em>band pass filters</em>.</p>
<p>Although some artists show performance with special devices for musical effects as described in the figure below,</p>
<p>it is usually hard to apply those effects in a real performance with limited devices and engineers.</p>
<p>In this case, we can use AMSS-Net to post-process the recorded clip for more dramatic introduction as follows.</p>

<ul>
<li>Methods based on neural networks sometimes suffer from artifacts, which are not present in the original source.</li>
<li>Although they sound negligible after a single manipulation task, they can be large enough to be perceived after progressively applying several.</li>
<li>To investigate artifacts created by progressive manipulation, we apply the same AMSS task ``apply highpass to drums’’ to a track in a progressive manner.</li>
