Re: Calculate / Display Byte Offsets in WAV Files by Audacit

Actually - I have found a possible doable solution meanwhile: I can mark a wav files with labels - didn't know that. The time resolution for the labels is xx.yyyyyy (6 digits after period) which should be a sufficient resolution to refind the time marked postion with time to byte calculation. As lab...

Re: Calculate / Display Byte Offsets in WAV Files by Audacit

Is this an Arduino project? If so, the audio quality is likely to be very poor whatever you do.PWM is a very poor way to encode audio (can be useful as a form of sound synthesis though). Sorry - PWM is not used for sound - PWM is used for the motor power control! No it is a Raspberry - Audio is dec...

Re: Calculate / Display Byte Offsets in WAV Files by Audacit

Have I got this right: You have some WAV files, and you want to know the number of bytes from the beginning of the file to a specific "start play time", and the number of bytes from the beginning of the file to a specific "end play time". Exactly this I want to figure out! Do you know a solution? B...

Calculate / Display Byte Offsets in WAV Files by Audacity ?

Hi All, I am a newbie to sound processing, please excuse silly questions! I am going to process (play) wav files in a C-programm. Want to activate (play) selected sound sniplets within a longer sound stream. Appropriate sniplets (with a START point and an END point in Byte offsets from the file enty...
