I'm currently building a Alexa application in Node with Lambda. I have the need to convert and merge several audio files. I'm currently creating an audio file using google text-to-speech (long story on the need for it) which I write to /tmp and pulling an audio file from s3 which I also write to /tmp. I'm then using sox to merge the two files (see below) and write back to S3 (currently public) which I then have hard coded to play that particular clip.
My question is if it is possible to play audio directly from the /tmp folder as opposed to having to write the file back to S3.
await lambdaAudio.sox('-m /tmp/google-formatted.mp3 /tmp/audio.mp3 /tmp/result.mp3')
// get data from resulting mp3
const data = await readFile('/tmp/result.mp3');
const base64data = new Buffer(data, 'binary');
// put file back on AWS for playing
s3.putObject(
Bucket: 'my-bucket',
Key: 'result.mp3',
Body: base64data,
ACL:'public-read'
,function (resp)
console.log('Done');
);
return`<audio src="https://s3.amazonaws.com/my-bucket/result.mp3" />`;

I usually upload the lambda function zipping the code and modules and in general all the files that my code requires.
https://developer.amazon.com/blogs/post/Tx1UE9W1NQ0GYII/Publishing-Your-Skill-Code-to-Lambda-via-the-Command-Line-Interface
So if you zip the /tmp directory and publish it as part of your lambda code the audio file will be accessible by your lambda function

unfortunately this audio dialog needs to be created on the fly, writing to the /tmp folder then read so uploading it isn't an option.
