All these years I was never moved in trying to use any other sound format except MP3.
The "lossy" MP3 format can actually change the actual sound quality due to its compression where lots of those so called not important data were removed.
In audio world the format normally used are classify into three types:
1) The Uncompressed or Original sound (WAV, AIFF, AU,PCM)
2) The Lossless format (FLAC, APE, WV, TTA, WMA Lossless, MPEG4, SHN)
3) The Lossy format (MP3, AAC, ATRAC, WMA Lossy, Mousepac)
I am not very familiar with the rest but only familiar with WAV, MP3, and WMA.
Most sound tracks available to be used in our BH are those of MP3 format.
This is mainly due to the type of amplifiers that are only designed to read the most common format ie MP3.
Once you purchase these suitable for MP3 amplifiers you are forced to use only MP3 sound format.
If you look up at the classification of sound formats you can see that MP3 is the most compressed and lots of losses.
When we term losses it means that more data are being removed in order to reduce the memory size of the actual song.
Please read this paragraph taken from Wikipedia website:
Lossy compressed audio formats
This is where we need to rethink of choosing the right type of amplifier(s) that can play those original uncompressed sound format.
No more MP3 type but maybe WAV format type.
I was very lucky to be approached by a local amplifier manufacturer who read my blog and contacted me in person wanted me to try his newly assembled product.
"Pak Harry the reason why I contacted you is because you are an inventor like me. You have invented and introduced many new things in swiftlet farming industry and I think I am similar as an inventor. My field is specially on sound system and solar energy."
He started sending his first batch of amplifiers and later another new model.
The best was the most recent.
"Pak Harry this latest black box have a unique ability to read those uncompressed sound format. It will be crystal clear and those birds might love the sound better that the MP3 sounds."
This newly assembled box can play four different sounds example two internal sounds and two external sounds.
You are given some wire connectors to connect any of them to those Hager timers for timing setting if you wish to.
The moment I got hold of the new untested amplifier I took it to the nearest BH under my care and replaced those old amplifiers.
I managed to get those WAV formatted sound, my favourite is the Pukau2 revision.
Started its virgin operation and from what I can observed they seems to attract more attention of those wild birds.
The next point of interest is to see how this new gadget will help to improve the number of birds entering and staying for the night within the next three months.
It will be something interesting and after telling the developer the story he quip:
"Pak Harry I am prepared to assemble the configuration of the best amplifier for BH. I need your feedback and if you have any preferred configuration let me know. I can put them together in just one week."
A very interesting word and I am not going to sit on it but will get him to put together a set that will allow me to play those WAV sounds for my internal, external and the last tango.
If you wish to have the best for your BH, I think this will one of the best option.
Remember you need to know how to develop or get the higher quality sound format first.
There is no use to go into this gadget and still playing those MP3 format.
It defeat the purpose of changing the amplifiers.
