海外TECH	DEV Community	Playing a full song, almost	https://dev.to/atornblad/playing-a-full-song-almost-48k	Playing a full song almostIn the previous article I described how to extract the raw sample data from a MOD file and how to play it The next step is to get the song data out from the MOD file and into a more useful data structure According to the sources I found see the previous article the song data is stored using bytes per pattern A pattern is a sequence of notes in channels each note being a of a bar Original MOD files contain four channels which means that a total of four samples or instruments can be played at the same time Each note is bytes each row contains notes and each pattern contains rows which makes bytes per pattern For each note the instrument index the period explained later and the effect also explained later are stored The instrument index is stored in the first bits of byte and the first bits of byte The period is stored in the last bits of byte and all bits of byte The effect is stored in the last bits of byte and all bits of byte Using this information I can write three new classes to store the song data Pattern Row and Note class Note constructor noteData this instrument noteData amp xf noteData gt gt this period noteData amp xf noteData this effect noteData amp xf noteData class Row constructor rowData this notes Each note is bytes for let i i lt i const noteData rowData slice i i this notes push new Note noteData class Pattern constructor modfile index Each pattern is bytes long const data new UintArray modfile index this rows Each pattern is made up of rows for let i i lt i const rowData data slice i i this rows push new Row rowData The constructor of the Mod class must also be updated to read the song data by calling the Pattern constructor for each pattern export class Mod constructor modfile Store the pattern table this patternTable new UintArray modfile Find the highest pattern number const maxPatternIndex Math max

instr length Extract the pattern data this patterns for let i i lt maxPatternIndex i const pattern new Pattern modfile i this patterns push pattern Playing one channel of one patternNow that the song data is stored in a more useful format it is time to play it The first step is to play one channel of one pattern The playback is driven by the process method of the worklet processor class For each sample that is played time moves forward by   or   of a second depending on the sample rate of the audio context Because of this we can use the samples as a time source and base all time calculations on the progression of samples The period of a note is the number of clock pulses of the Amiga Paula co processor which run at half the speed of the main CPU clock On a PAL Amiga the main CPU clock frequency is    Hz so the co processor frequency is    Hz A sample playing with period  the period of the note C will play at      Hz For an audio context with a sample rate of   Hz this means that each sample will be output     times before the next sample is output These calculations must be done each time the period changes To step forward in the song i also need to keep track of the current position in the song the current row to play and how many samples are left to play before moving to the next row For now the number of samples per row is calculated using the BPM of and the sample rate of the audio context const PAULA FREQUENCY class PlayerWorklet extends AudioWorkletProcessor constructor super this port onmessage this onmessage bind this this mod null onmessage e if e data

send the complete mod data to the worklet and not just one instrument I also need to send the sample rate of the audio context so that the worklet can calculate all timings correctly Here are the changes to the main thread code Load Elekfunk from api modarchive orgconst url const mod await loadMod url Play a sample when the user clickswindow addEventListener click gt audio resume player port postMessage type play mod mod sampleRate audio sampleRate After these changes when you click the browser window the first channel of the song starts playing However the timing is a bit wrong and some of the notes are not playing correctly This is because no effects have been implemented yet The Elekfunk song uses the currently unimplemented Set Speed effect to speed up the playback and that s why the timing is wrong Also to really enjoy the song all four channels need to be mixed together The last changes I make in this post are to create a four channel mixer and to implement the Set Speed effect Mixing multiple channelsTo mix the four channels of the song together I need to keep track of the instrument and period for each channel Each channel needs to have its own sample index and move forward in the sample independently of the other channels I create a Channel class to keep track of this information and I create four instances of this class in the worklet The nextOutput function now loops over all four channels and adds the output of each channel together To limit the output to the range of to I use the Math tanh function which is a hyperbolic tangent function It has the nice property that the output is always between and and the output is also scaled to the input class Channel constructor worklet this worklet worklet this instrument null this period this sampleSpeed this

ways If the value is less than it sets the number of ticks per row If the value is greater than or equal to it sets the number of beats per minute A tick is a concept of the MOD format and is normally a th of a row Most older MOD files never change the BPM but instead changes the number of ticks per row to speed up or slow down the song A lot of effects perform calculations based on the number of ticks per row so it s important to implement this effect I ll start by adding an effect method to the Channel class which I can use to implement all the effects I ll also add a setTicksPerRow method and a setBpm method to the PlayerWorklet class which I can use to update the number of ticks per row play note if note instrument this instrument this worklet mod instruments note instrument this

instruments play correctly and the song is played at the correct speed but there are still a lot of effects missing Those will be the subject of the next couple of parts of this series You can try
