Home Forums Sparkfun MP3 Shield Library Support Forum TotalLenght of a Mp3 file ? Reply To: TotalLenght of a Mp3 file ?


There are several “getter’s” included in the library. Note several of them only work for certain file formats. Obvious, since not all contain wrappers that include everything. The entire library of code is document ed http://mpflaga.github.io/Sparkfun-MP3-Player-Shield-Arduino-Library/

I would recommend searching the web documentation for the following the search is in the upper right.

void SFEMP3Shield::getTrackInfo(uint8_t offset, char* infobuffer){

void SFEMP3Shield::trackArtist(char* infobuffer){

void SFEMP3Shield::trackTitle(char* infobuffer){

void SFEMP3Shield::trackAlbum(char* infobuffer){

void SFEMP3Shield::getAudioInfo() {

void SFEMP3Shield::getBitRateFromMP3File(char* fileName) {

int8_t SFEMP3Shield::getVUmeter() {

int8_t SFEMP3Shield::setVUmeter(int8_t enable) {

int16_t SFEMP3Shield::getVUlevel() {

You may need to also do some direct file access and properities and some math to calculate totals. Note some file formats have variable bit rates. These may change on the fly.
