Jan 23, This library was intended to be a simple and user friendly wav audio player using standard Arduino libraries, playing bare-bones standard format WAV files.

Many of the extra features have been added due to user request, and are enabled optionally in pcmConfig. Most of the extra features require more memory, more program space, and in some cases, more processing power for playback Some of them are still being fine tuned. Please keep this in mind when enabling these features. See pcmConfig. This library outputs WAV data to two timer pins by default, although only one is fully enabled by default.

These modes require additional resources and processing power since double the data must be read from the SD card.

Mono tracks can be played in Stereo mode, not so in reverse. The operation can be a bit difficult to explain, but here goes:. The files must be included in the sketch. Note: Audacity is the only supported program to add, modify or edit metadata.

Mainly for use with Uno, Nano etc with only one bit timer. Trying to reduce all of the popping noises created from PWM has been a struggle, but I've identified and addressed 4 main sources:.

These features will generate standards compliant WAV files. Raw data from analog inputs or other sensors or information sources can be written to the file to generate digital audio that can be played on any device that supports WAV files, or easily converted to other formats.

Note: More wav formats etc. Skip to content. Advanced Features Jump to bottom. Advanced features of the library This library was intended to be a simple and user friendly wav audio player using standard Arduino libraries, playing bare-bones standard format WAV files. The complimentary pin must be set as an output to enable: eg: Arduino Uno Single Output : audio. Multi Mode Multi Mode enables simultaneous playback of two audio tracks. Functions: The functions in multi mode are slightly different than standard mode: audio.

Modes Simplified: Normal mode 2 pins, one track 1 or 2 speakers Normal mode Stereo 2 pins, one track 2 Speakers, non complimentary pin to ground Normal MODE2 Stereo 4 pins, one track 4 Speakers OR Complimentary output pin-to-pin with 2 Speakers Multi mode 2 pins, two tracks 1 or 2 speakers Multi mode Stereo 4 pins, 2 tracks 2 or 4 speakers, non complimentary Multi MODE2 4 pins, 2 tracks 2 complimentary, or 4 non complimentary Note: All 4-pin modes require a board with two or more bit timers.

Stereo and Bit Playback These modes require additional resources and processing power since double the data must be read from the SD card. This will produce a stereo output for two speakers, connected from speaker pin s to ground, or a single bit output using a resistor ladder. The timer and pins are specified by the speakerPin2 variable.

Complimentary timer pins need to be set as output pins manually. This provides output for four speakers, connected from speaker pin s to ground or a single bit output for each track. Metadata ID3v2. Functions: listInfo - Reads LIST tags into a character buffer, returns the length of the tag id3Info - Reads ID3 tags into a character buffer, returns the length of the tag getInfo - Searches for both tags and reads into a character buffer, returns the length of the tag.

ID3 is searched first. Search LIST info only and print song name over serial: char info[32]; audio. Search ID3v2. This is usually not the best solution. Playback speed will be slightly different than with bit timers. TIMER2 playback supports non-standard sample rates: Pages: [1]. I've followed the tutorial, but my speaker won't play music.

I think I converted the file correctly and have all the pins plugged into the correct place. I can't think of anything else to make it work, so I thought I should ask for help on a forum. Here's the code: Code: [Select]. Well good for using code tags but that is not nearly enough information to spot what you have done wrong, because we have no idea what you have done, Quote.

Thanks for the reply! I used the following settings for the conversion following the tutorial : Change bit resolution to " 8bit ". Change sampling rate to " Hz ". Change audio channels " mono ". Click on " Show advanced options ". PCM format " unsigned 8 bit ". Here are some photographs of my wiring:. I don't know if this is your problem but you can't connect an 8-Ohm speaker directly to the Arduino. If you have powered computer speakers you can use those. Or, you can put a Ohm or higher resistor in series with the speaker.

That will lower the volume. Or, you can directly drive a piezo transducer. I don't recommend connecting to your home stereo because it puts-out PWM, not true-analog, and "bad things" could happen. Thanks for that but you know we can only know what you tell us. Thanks again for helping! I've tried tried using a ohm resistor in series with the speaker, but it didn't work. Still coudn't hear any sound. As for the mix of tutorials, I mainly used this one.Recent Updates Many new features have recently been added, and are in development.

Set volume level audio. Can be changed during playback for full control of looping.

Advanced Features

The isPlaying disable or noInterrupts functions can be used to prevent parallel code execution. Pop or click when playback is started or stopped: Ramps are built into the library to prevent popping when PWM is engaged, disabled, and between music tracks of the same sample rate.

Popping or clicking when music is playing If pops or clicks are heard during playback, it is most likely that buffer underruns are occurring or the volume is just too high.

The value in define buffSize can be increased to provide additional memory for playback, which will reduce these issues. Audio can be encoded at a lower sample rate otherwise.

Arduino Library – TMRpcm

The first thing to check is memory usage, since nothing will work if out of memory. The library uses two timer pins by default. This may interfere with other libraries that use it. Error message when compiling: "Has no member named Check the defines in pcmConfig.

What great releases will we have in 2017. Will The CV rework bring us our second premium carrier. What do you guys think and hope we will see. But in case you don't know, Shinano was an aircraft carrier converted from a Yamato-class battleship hull.

It was ridiculously well-armored. Planes were good, but there were no replacement planes at all. Heavy armor made it a good ship for ramming the enemy when you lost all your planes.

Only down side was detection range, fear of fire and lack of plane capacity. Yes, you can actually spec her into secondary. And hopefully an Italian premium preparing for the Regia Marina next year.

AA power creep, shitty credit and experience. Though Pola or Roma would be good too.

We are getting good Zeppelin but I think it would be a while until Aquila thought I think a premium DD, CA or BB are much more likely. I don't even play carriers but I'd buy Aquila because she's in my opinion one of the best looking carriers. And since we've both got the same flair now, it's even more confusing. I hope you've learned your lesson Syanda. Go reflect on your actions for trying to impersonate others.

Note the unusual gun-forward layout, designed to allow unobstructed flight operations aft. Tone and Chikuma served as scouts for the Japanese carriers and launched floatplanes to scout Pearl Harbor just before the attack. To honor this unusual design, Wargaming is experimenting with a hybrid cruiser-carrier, which has been in the game files for months. According to Q the main difficulty now is the "insane" UI. It seems likely Tone herself is on hold until the CV UI rework which was scheduled for this year.

Which I suppose would fit the ship in as a Scout roll, which would remove some pressure from DDs and the CV for spotting. I suspect they'll be fighters of some sort that can double as scouts, though bombers with rather small bombs isn't out of the question. It flies there, scouts, and reports back, likely with limited range. Mogami and Hyuga are better hybrids. She was just a scout heavy cruiser.You can change the color, thickness, or fill of these shapes by using the tools that appear on the right side of the toolbar when you've selected them.

We had a lot of trouble deciding on which tour to do and Sara was very patient in answering our questions and provided excellent advice on what she thought would be the best tour for what we wanted and in the time we had. I couldn't have asked for more from Sara, she went above and beyond to help us, and I'm very grateful for all she did as everything ran so smoothly which no doubt made the trip more enjoyable.

I could not have organised such an awesome trip myself all the way from Australia.

I wanted to go to Longyearbyen, the northernmost town in the world, on an island about 1,000 miles north of Oslo, Norway, in December. I knew nothing about preparing for a trip like that, including what to wear for the Arctic cold weather. Luckily, I found Nordic Visitor. Kolbrun helped identify a number of activities for me to do (including dogsledding), and arranged for a great hotel, airport pickup, etc. She was very patient with me (I had tons of questions) and gave me great guidance on how to dress and prepare for the trip in general and the specific activities.

I received a great itinerary in advance, detailing where to meet tour guides every day, etc. The trip went without a hitch. One activity (snowmobiling) was cancelled due to weather, and I received a very prompt refund for the activity shortly after I got back. I did the Iceland Winter World tour. It hit up all of the big attractions and diverse natural beauty of Iceland. Loved the Golden Circle tour and the Blue Lagoon spa, especially. The tour guides were friendly, informative, warm, and professional.

The tours were so organized and streamlined - you could explore, relax, and enjoy yourself, without stressing about coordinating anything. Shoutout to Larus at Nordic Visitor - he's awesome and was always available to answer my questions as quickly as possible.

Alexandra was really helpful when our flight was delayed and we were messed around by the airline. Even though our flight did not arrive till gone midnight (9 hours late.

The maps and books provided were excellent and allowed us to plan our time and get the most out of the holiday. Overall the accommodation was excellent and experience was amazing. We had a wonderful holiday in Iceland thanks to Nordic Visitor. What an amazing country. I have eaten Puffin, Horse and Reindeer which I hadn't done in the past. We saw the Northern Lights, geysers, glaciers, and waterfalls.

My wife and I decided to go to Iceland for our honeymoon, and spent some time researching various travel agencies that would help you book a tour of the country. We decided to go with Nordic Visitor's "Winter Romance" package, and it was just perfect. Nordic Visitor was very thorough in booking lots of wonderful places for us to travel to (in our own rental car, rather than on a tour bus or something), and took all the stress out of trying to plan the tour ourselves.

Corresponding with them was fast and easy and they made sure we had everything necessary in order to have the best trip possible. If you decide to plan a similar trip with them, I'd definitely recommend opting for some of the optional activities -- snowmobiling on a glacier is something we'll never forget. Hotel choices were very good as far as location and amenities. Helena was very helpful in making the booking process quick and easy.

Helena made some in-trip adjustments for us that were very helpful. Hotels were fabulous with a great view in almost all of them. The travel agent was amazing.
