This is what the Wav files sample at in the FPSC Audiobank the one's in Wav format
Bite Rate: 1411 kbps
Audio Sample Size: 16 bit
Channels: 2 (stereo)
Audio Sample Rate: 44 kHz
Audio Format: PCM
Explaination---------
Pulse Code Modulation (PCM) is a subclasses of the Microsoft waveform (.WAV) file format. In PCM, data for .WAV files is stored using linear samples.
How PCM Works
PCM works by taking discrete samples at even intervals (called the sampling rate). Common intervals are 11 kHz, 22 kHz, and 44 kHz. The higher the sampling rate, the better the representation of the original analog wave and the better the sound quality. Each sample is a real number with infinite resolution from +1.0 of full-scale value to -1.0 of full scale value. Because these must be stored as finite-precision digital numbers, the data is truncated to either 16-bit PCM or 8-bit PCM, commonly called 8- and 16-bit samples. 16-bit data has more resolution, so the digital waveform sounds better. 8-bit PCM has less resolution, causing audible hiss in the waveform. It also requires less disk space.
In the attributes there are 3 ‘options’ you can choose from… Bits, Hz and Mono/Stereo.
NOTES: (You can learn and apply)
The more Bits. The larger the .WAV file will be. (more Kbs)
The more Hz. The larger the .WAV file will be. (more Kbs)
Stereo format makes larger .WAV files then Mono format.
When converting a .WAV, you cannot improve quality by making it more Hz.
When converting a .WAV, you cannot improve quality by making it more Bites. (8 bit to 16 bit etc.)
When converting a .WAV, you cannot improve quality by changing Mono format to Stereo format.
Microphones can ONLY record in Mono format. (Unless you have 2 microphone recording function). Some software like FL Studio has the mono feature in the software.
What does this all mean…
Taking an 8 bit, 11,025 hz, mono wav and converting it to 32kb 22,050 hz, mono.
DOES NOT improve quality.
ALL IT DOES IT MAKE A LARGER file! In fact, it has to 'make up' more bits and therefore, can
'ruin' a sound file.
** Quality of a .WAV always depend on how it was recorded in the first place
** Making a wav format more or less bits or hz can ruin the sound quality of a wav. I would recommend that you test the changed format before you destroy or delete the original sound file.
** Convert attributes to closest original format possible!!!!
I typically use the above attributes as described in ‘step by step’ directions rather then spend the time on each individual wav. Across the board this seems to be closest average to all wav formats. Unless it is a song originally recorded in stereo. Then I will atleast keep the stereo format.
