Comment (by michael.heuberger):

 some context: these pcm's come from the web, were initially raw webAudio
 samples in Float32Array's which have been converted to 16 bit signed
 integers with this JS function:

 {{{
     this.toBuffer = function() {

         var l   = float32Array.length,
             arr = new Int16Array(l)

         // this uses lots of CPU and should be optimized
         for (var i = 0; i < l; i++) {
             arr[i] = Math.min(1, float32Array[i]) * 0x7FFF
         }

         return toBuffer(arr)
     }
 }}}
