I can successfully upload audiofiles to AWS S3
, however the files do not play whether downloaded or played in the browser. The files do have a filesize
.
I’m uploading an audioBlob
object to AWS S3
:
const [audioBlob, setAudioBlob] = useState(null)
const submitVoiceMemo = async () => {
try {
await fetch('/api/createVoiceMemo', {
method: 'PUT',
body: audioBlob
})
} catch (error) {
console.error(error)
}
}
This is the API
Route:
module.exports = requireAuth(async (req, res) => {
try {
AWS.config.update({
accessKeyId: process.env.AWS_ACCESS_KEY_1,
secretAccessKey: process.env.AWS_SECRET_ACCESS_KEY_ID,
region: 'us-east-2',
signatureVersion: 'v4'
})
const s3 = new AWS.S3();
const uuid = randomUUID()
const s3Params = {
Bucket: 'waveforms',
Key: `voicememo/${uuid}.mp3`,
Body: req.body,
ContentType: 'audio/mpeg',
ACL: 'public-read'
}
await s3.upload(s3Params).promise()
} catch (e) {
res.status(500).json({ error: e.message })
}
})
As per this question, I have confirmed that req.body
is a string
.
The file being received by S3
has a filesize
and the correct contentType
when checked in the S3 console
. It just isn’t playable when downloaded or played directly in the browser.
Below is how audioBlob
and also audioFile
(an MP3) are generated (Basically the user records a voice memo and when they click stopRecording
, raw audio is stored as state
):
const stopRecording = () => {
recorder.current
.stop()
.getMp3()
.then(([buffer, blob]) => {
const file = new File(buffer, 'audio.mp3', {
type: blob.type,
lastModified: Date.now()
})
setAudioBlob(blob)
const newBlobUrl = URL.createObjectURL(blob)
setBlobUrl(newBlobUrl)
setIsRecording(false)
setAudioFile(file)
})
.catch(e => console.log(e))
}
How can I correctly store audio generated on the front-end, in S3
?
