I had Text-To-Speech (TTW) working really well with squeezelite and Home Assistant<\/a> on a Raspberry Pi <\/a>3B with max2play (which now looks sadly defunct). I thought I would pep things up a bit and use a RPi4 elsewhere as a Speaker for HA so my music was not constantly destroyed. <\/p>\n\n\n\n

Getting squeezelite to work was easy but could I get TTS to work? The mp3 file was created but squeezelite looped when trying to play it. Sad times. <\/p>\n\n\n\n

I worked out that it played fine when the sample speed was increased and in all my searching hit upon the concept of “Upsampling”. Hmmm. Since I had originally used “apt get install sqeezelite -y” and found it hard to find any settings at all and had not yet really understood docker I took this opportunity to move to a docker setup. Happily one of the settings allowed the magic “Eq” that got things rolling along.<\/p>\n\n\n\n
