    <p>I want my app to react on a load sound like a clap. The problem is, that <code>getMaxAmplitude()</code> reaches it's maximum of 32762 even when talking in a normal voice which is <code>&gt;= my "allMaxAmpli"</code> variable set in the config mode.</p> <p>The media recorder is set up like this:</p> <pre><code>mrec = new MediaRecorder(); mrec.setAudioSource(MediaRecorder.AudioSource.MIC); mrec.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP); mrec.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB); [..] mrec.setOutputFile(audiofile.getAbsolutePath()); mrec.prepare(); mrec.start(); </code></pre> <p>and the check is done like this (abstracted):</p> <pre><code>int maxAmp = mrec.getMaxAmplitude(); if (maxAmp &gt;= CalibAmp) Log.v("ID", "Max Amp is greater!"); </code></pre> <p>Did i miss something? </p> <p>Is there some other way to measure the volume, or increasing the limit for getMaxAmplitude? I thought about using AudioRecord, but then i'd have to calculate the amplitude by hand. I wanted to save myself from that.</p> <p>I searched for quite a bit before considering posting, but i was unable to find anything. Any help would be appreciated.</p> <p>/Edit: If i calculate the decibel out of the amplitude, will this get other values? This might solve the problem then.</p> <p>/Edit2: I calculated the decibel out of the amplitude, but the problem persists, since the Amplitude is so high all the time. Nobody has an idea? :/</p> <p>/Edit3: After testing some other Apps it seems that this is a general problem with Android. So that is why every sound measuring app is free..</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
